High-pressure relief valve.

The launch of a full-flow high-pressure relief valve (FHPRV) for the Danfoss H1B bent-axis motor has been announced. The FHPRV joins the counterbalance valve (CBV) in a portfolio of valves designed to enable the use of Danfoss high-power axial piston motors in open-circuit systems. The FHPRV enables machine designers to leverage the benefits of the H1B motor’s compact design and outstanding efficiency while also providing overpressure protection in high-power applications.

The FHPRV is a bolt-on valve that provides high-flow pressure relief at the motor, which is critical for motor protection in demanding applications. In the event of an extended overpressure situation, the valve enables the passage of up to 600 liters per minute of flow, depending on size, preventing damage to the motor and pump. The flow rate is among the highest available for this type of valve.

The compact solution offers full-flow relief functionality without a significant increase in motor size or circuit complexity. Other solutions, such as remote-mount manifolds, require more space and can increase cost and complexity.

Commonly used in closed-circuit propel applications, axial piston motors such as Danfoss H1 motors are also ideal for high-power open-circuit systems, including drilling functions, crushing and shredding functions, heavy-duty excavator attachments, and forestry applications.

“While typical open-circuit applications can make use of low-speed high-torque motors, higher pressure applications require higher power axial piston motors,” said Kenny Befus, High-Power Portfolio Manager, Hydrostatics division, Danfoss Power Solutions. “Danfoss H1 motors feature a delta pressure rating of up to 450 bar, 480 bar absolute, making them ideal for these scenarios. And now, with our full-flow high-pressure relief valve, we can provide a better match when it comes to power and pressure.”

The FHPRV can be stacked with other valves, such as the CBV, providing additional functionality based on application needs. It can also be used in closed-circuit applications.

The FHPRV is available in four configurations to suit the range of H1B motor displacements. DN19 works with the 60-cc motor, DN25 works with the 80-cc and 110-cc motors, DN32A works with the 160-cc motor, and DN32B works with the 210-cc and 250-cc motors.

Pressure Relief Valve.

Deliver leak-tight service at very high pressures for hydrogen storage, transport and refuelling stations.

The Anderson Greenwood Type 84 Pressure Relief Valve (PRV) has been introduced by Emerson. This is specially designed to protect tanks and vessels used in hydrogen and other high-pressure gas applications. With Arlon® 3000XT thermoplastic seating and ASME SA-479 Type S21800 stainless steel spindle material, the Type 84 PRV delivers exceptional leak-tight performance, resistance to embrittlement, optimum seat tightness, high reliability and long service life.

PRVs are frequently used in traditional applications, but they are not designed to handle extremely small molecules at very high pressures. Therefore, they are not ideal for hydrogen gas, which can diffuse into metals and cause embrittlement of PRV internals, increasing the risk of leaks, failures and safety problems.

To address these and other issues, Type 84 PRVs are constructed for high-pressure gas applications, with a range of 6,000 pounds per square inch gauge (413 bar gauge) to 20,000 psig (1,379 barg) for H2 and He, and a range of 6,000 psig (413 barg) to 21,756 psig (1,500 barg) for all other gases. It reaches full lift at less than 5% overpressure to protect the vessel or tank to which they are affixed, with zero leakage at 90% of set pressure. The valves feature a unique cartridge assembly design to apply uniform spring pressure, resulting in secure seat sealing and leak-tight performance. They are factory tested with helium and nitrogen, both accepted industry-wide as a substitute for hydrogen.

Anderson Greenwood Type 84 valves comply with key industry standards for safety and performance, including American Society of Mechanical Engineers (ASME) Section VIII and XIII, National Board of Boiler and Pressure Vessel Inspectors (NB) certification, and American Petroleum Institute (API) 527.

Pressure valves for high-precision manufacturing.

Enables quick startup, monitoring and control directly on a PC.

The AVENTICSTM Series 625 Sentronic Proportional Pressure Control Valves has been announced by Emerson. With a control deviation of less than 0.5%, the new valves are designed to deliver highly accurate, electronic proportional pressure control and provide the flexibility needed to support sophisticated pneumatic control engineering applications. Data acquisition software (DaS) software included with Series 625 Sentronic valves also make it possible to quickly startup, monitor and control valves directly on a PC.

“In high-precision equipment, such as that used for flame cutting and laser eye surgery, accuracy and control are critical,” said Nicolas Jacquet, director of product management for Emerson’s discrete automation business. “Series 625 Sentronic valves are engineered to precisely control pressure, flow rate, power, speed, distance and angular positions. As part of the extensive AVENTICS portfolio of cylinders, valves, air preparation and pressure regulators, the Series 625 Sentronic is a core technology for factory automation.”

Four valve sizes from 1 millimeter up to 20 mm support a comprehensive range of flow rates, from 55 liters per minute to 4,700 l/min. Pressure capabilities range from vacuum levels up to 50 bar, which can reduce the overall number of valves required for a machine design. Housing material is available in brass, aluminum or stainless steel and sealing material in nitrile (NBR) or fluoroelastomer (FKM) options. There are also three sets of connectors, M12 5-pin, M12 8-pin and M16 7-pin.

As development and manufacturing phases continue to get shorter, fast startup procedures and reliable, controllable manufacturing processes are more important than ever. Using the DaS software, operators can diagnose, control, repair or individually configure valves. They can also perform cascade controls when applications require exceptional precision and other complex control loops. The expanded range of diagnostic and monitoring functions include input pressure, commanded pressure, internal temperature and ethernet communication.

Smooth and even control.

Danfoss Power Solutions has partnered with Australian crane manufacturer Franna to improve the performance of its MAC 25 crane. With the PVG 48 proportional valve at the heart of the work and steering subsystems, Danfoss is delivering a reliable, precise, future-proof solution.

Franna, a Terex brand, is a leading manufacturer of pick and carry cranes with a rich heritage of design and engineering excellence. For more than 40 years, Franna has been a leader in the Australian market, and today its products are at work in more than 30 countries across the globe.

Franna’s MAC 25 mobile articulated crane features a maximum lifting capacity of 25 tonnes (27 tons) and a maximum boom length of 18.4 meters (60 feet). The crane offers maximum safety, excellent roadability, intuitive operation, and unmatched versatility. True to the company’s heritage, the crane’s design has been tested, proven, and continuously improved over the years.

In 2021, Franna began looking at other options for the MAC 25 crane’s main control valve. The company required a solution that was precise, reliable, and future proof to accommodate increasingly sophisticated electronic control systems. The Danfoss PVG 48 proportional valve, then in development, emerged as the superior solution.

PVG 48 is a pre-compensated proportional control valve for applications requiring flow rates of up to 180 liters per minute (47.6 gallons per minute). The latest member of the PVG load-sensing valve family, PVG 48 is ideal for machines such as wheel loaders, aerial lifts, and cranes in which precise flow and controllability are essential.

Danfoss launched the PVG 48 valve to the general market in June 2023 with Franna as a key pilot customer. On the MAC 25, the valve turns operator joystick inputs into quick, accurate boom movement.

“The PVG is extremely precise and reliable. It does what you want it to do repeatedly,” said Adam Murchie, project engineer, Franna. “It’s the ideal choice for MAC 25 and likely to end up in other of our cranes, too – not least in future launches where more advanced electronic controls are key. We wanted a future-proof valve. PVG 48 is it.”

Franna MAC25 Crane

The PVG 48 valve integrates easily with electric actuators, sensors, and digital controls, opening a range of possibilities. One of them is to automate certain machine functions so the crane assists – or even takes over from – the operator. Such a function can be advantageous in many situations, particularly when instant reaction is required to ensure safety.

With the change to PVG 48, Franna also switched to Danfoss counterbalance valves. Together with PVG 48, they ensure smooth and safe activation of the crane’s boom.

“Controllability is smooth and even – very refined,” said Quentin Bourke, product support technician, Franna. “The initial tiny bounce on the front tires, which you sometimes see when operators raise or lower the boom, is completely gone. Extension or subtraction of the boom is impressively smooth, too.”

Bourke adds that initial feedback from crane operators using MAC 25 with a PVG 48 and Danfoss counterbalance valves is positive, too.

“Together with Danfoss, we’ve managed to create the exact kind of MAC 25 crane feel that we hoped for,” Bourke said. The these proportional valve is already at work in more than 100 of Franna’s MAC 25 cranes throughout Australia.

Digital valve controller is a first.

Offers Advice at the Device technology with real-time analytics for valve health diagnostics and prescriptive corrective actions.

The Fisher™ FIELDVUE™ DVC7K Digital Valve Controller, a new design improving upon 30 years of field-proven innovation has been announced by Emerson. The DVC7K features Advice at the DeviceTM technology with embedded computing and analytics that convert raw data into actionable information locally with Bluetooth® capability, within the device. This means maintenance personnel can receive the data via their phone, tablet, or computer wirelessly without having to be in a control room at the plant location. 

The new valve controller technology improves the performance, reliability, and uptime of both on-off and control valves—and by extension an entire process plant or facility—in a wide variety of process industry applications, and provides the information required to create streamlined work processes.

Digital valve controllers are available as accessories for control and on-off valves to provide local analysis of valve data, digital communications with host systems, and other features. These features improve uptime by alerting personnel to developing problems, reduce maintenance costs by providing the actionable information required for proactive rather than reactive maintenance, and cut troubleshooting time in the event of an issue by providing recommended corrective actions. For example, a control valve may be reacting slowly to commands requiring it to move, which is often an early sign of impending issues. The DVC7K will recognize this type of condition, alert personnel, and provide recommendations for fixing the problem.

The DVC7K interprets data to create an optimized path to action by combining patented technology, experience-based algorithms, and continuous real-time analytics with flexible connectivity and easy integration. It uses powerful, real-time, and onboard edge computing to analyze issues and create actionable information, providing real-time awareness of valve health by analyzing data locally via its on-board diagnostics. If analysis reveals a problem, an alert is created, which can be viewed locally or remotely, providing the information required to create streamlined work processes that save time and money. All alerts include recommended actions to fix the problem, a new feature for digital valve controllers, and unique to the industry.

Previously, digital valve controller data had to go to a host system to be processed and prepared for viewing, however, with the intelligence of this system, data is now accessible without requiring access to the host software. All information can be viewed at the DVC7K’s local user interface, nearby via Emerson Secure Bluetooth® wireless technology, or remotely after it is transmitted via a wired digital network to a host, such as a distributed control or asset management system.

The local user interface provides indication of valve health at a glance via LEDs, and users can drill down from the interface home screen to find more information. Emerson Secure Bluetooth enables access to one or more digital valve controllers at distances up to 30 feet from any device capable of supporting Bluetooth, such as a smartphone or tablet. Whether the information is viewed locally, nearby, or remotely, plant personnel can use it to drive awareness of valve health.

With increased remote connectivity and Advice at the Device local diagnostics, flexibility increases, providing the information needed for fast decisions and quick action to address arising issues. The DVC7K can be specified for all new valve purchases, and it can be retrofitted to most existing valve installations, in either case quickly and easily commissioned via the local user interface. With over three million FIELDVUE units sold and ten billion hours plus of field operation, long-term reliability and performance is proven in use, a key requirement as Fisher and other Emerson valves are often used in critical process industry applications.

Integrated manifold for respiratory therapy devices.

The ASCO Series 588 manifold reduces manufacturer engineering and assembly time, improves energy efficiency, product lifespan and reliability of devices.

The ASCO™ Series 588 Stationary Oxygen Concentrator Manifold has been announced by Emerson. This is the healthcare industry’s first turnkey manifold solution designed to optimize respiratory therapy device designs and accelerate product speed to market. Oxygen concentrators must quickly reach patients who rely on them, so it’s critical that they are readily available and operate reliably. The Series 588 manifold is specially designed to simplify device engineering and assembly and improve device energy efficiency, lifespan and reliability.

Without an integrated manifold, manufacturers must mount valves individually into the fluidic path of oxygen concentrators and attach dedicated tubing to each orifice. Alternatively, the small, lightweight architecture of the Series 588 manifold easily integrates into the fluidic path of oxygen concentrators, significantly reducing engineering and assembly time for medical equipment manufacturers. The Series 588 features two robust general service valves that precisely control the flow of air between the compressor and the sieves. The manifold fastens easily into the fluidic path, and a barbed port design makes it simple to connect tubing.

“Oxygen concentrators are essential to the health and well-being of patients with chronic respiratory disorders, so it is critical they are readily available for therapy. However, one of the most important aspects of these devices is an intelligently designed fluidic path, and that takes time,” said Thomas Beck, product marketing manager for analytical and medical at Emerson. “With the ASCO Series 588 Manifold, our fluidic path experts have designed a low-power, robust solution that can save medical manufacturers time and lifetime costs. Manufacturers can quickly and simply install the integrated manifold by connecting just a few tubes.”

In addition to simplifying design and assembly, the Series 588 can help improve device energy efficiency and reliability while lengthening product life. The manifold’s compact footprint can enable smaller device designs without sacrificing performance. The valves’ low power demand can extend device battery life and time between charges, which can set a manufacturer’s product apart from competitor offerings. And the high reliability of the valves can lengthen the overall lifespan of the oxygen concentrator and minimize manufacturer lifetime costs.

Valve certified for Hydrogen applications.

Bureau Veritas Italia approval has been granted for Emerson's BM6X Series Slam-Shut valve for use in applications with up to 100% hydrogen and pressures up to 100 bar was completed in December 2022. The certification was achieved as a result of the commitment of Emerson and Bureau Veritas Italia to ensure suitable products are available for use in new hydrogen infrastructure. The certification granted to the Emerson BM6X Series Slam-Shut valve confirms the verification of material suitability, based on internal and external seal tests performed at the Emerson production plant in Castel Maggiore, Bologna, Italy.

BM6X Series Axial Flow Slam-Shut Valve

Emerson is working with its customers to develop a hydrogen ecosystem, starting with research and innovation, and scaling up production and transportation. These efforts are an important focus of the European Union’s strategy on hydrogen, adopted in 2020, and of similar efforts in other countries and regions worldwide. Certifying key components, such as the Emerson BM6X Series Slam-Shut valve, is a critical step for these types of projects.

“The Bureau Veritas procedure, relating to the issue of Type Approval for hydrogen-operated actuators and valves, defines the audit process for the issue, maintenance and renewal of the certification for actuators and valves used with hydrogen or hydrogen mixtures,” says Giuseppe Signoretta, hydrogen technical manager, Bureau Veritas.

“This procedure supports the certification of products ready to be used in the hydrogen field, and it provides a suitable tool for the concrete implementation of the European plans for energy independence and reduction of CO2 emissions. The collaboration between Emerson and Bureau Veritas demonstrates a concrete commitment to offer suitable and safe products for natural gas distribution networks,” adds Signoretta.

“To ensure product quality, safety and conformity, Emerson is collaborating with the testing and certification agency Bureau Veritas Italia, and it has developed internal procedures to assess the suitability of products to be used in gas infrastructure applications,” said Oscar Bressan, standardisation and product engineer with Emerson’s pressure management research and development team.

“The Emerson procedures describe the requirements, tests and inspection methods for metallic and non-metallic materials, as well as internal and external sealing necessary to use pressure control products in contact with natural gas and blended hydrogen, or pure hydrogen. After the first certification obtained for the Emerson BM6X Series Slam-Shut valve, Emerson will continue to certify other equipment used in hydrogen infrastructure to ensure sustainability and reliability for this rapidly developing market,” concludes Bressan.

The Emerson BM6X Series Slam-Shut valve has multiple applications throughout gas transmission networks, regulating stations and end use infrastructure. For example, natural gas transmission and distribution companies can blend hydrogen into their distribution systems, reducing emissions when the blended mixture of hydrogen and natural gas is burned in homes for cooking, heating and other uses. Industrial end users can reduce emissions by using a mix of hydrogen and natural gas as fuel for turbines used for power generation.

Pressure relief valves reinvented!

Two new-to-the-world technologies for the Crosby™ J-Series pressure relief valve (PRV) product line have been announced by Emerson. The first is a Balanced Diaphragm, which eliminates the need for bellows in PRVs, while providing balanced operation against backpressure to lower cost of ownership and enhance performance. The second technology is Bellows Leak Detection, enabling remote detection of bellows ruptures in PRVs, with the capability to reduce and accurately calculate volumetric emissions in real-time.

Top: Bellows Leak Detection;
Below: Balanced Diaphragm

“With the growing global emphasis on sustainability, an increasing number of PRVs that currently vent to the atmosphere will require connections to flare systems to curb emissions. The resulting higher backpressures will push the limits of existing PRV designs, and the Balanced Diaphragm and Bellows Leak Detection breakthrough innovations will help our customers address this need,” said Judson Duncan, president of Emerson’s pressure management business.

Where backpressure is present, spring-loaded PRVs often utilise bellows to ensure balanced operation. Data analysis from 30,000 PRV service records across different industries and valve brands shows a bellows failure rate between 2% and 6%. In other words, a plant with 1,000 bellows PRVs may have between 20 and 60 PRVs continuously operating with damaged bellows. The most common causes of bellows failures are excessive backpressure and rapid cycling. Ruptured bellows will cause fugitive emissions and may prevent valve operation at the designed set pressure, with the risk of overpressure events.

The Crosby Balanced Diaphragm can replace bellows in PRV applications to address these and other issues. Its innovative design extends the backpressure limits from 60% to 80% and increases the Kb backpressure correction factor by up to 15%, expanding the application range of spring-loaded PRVs. The Kb factor is used to size PRVs when they are installed in closed systems subject to backpressure. Extending the backpressure limit and increasing the Kb factor often permits the use of smaller valves. In addition, diaphragms are inherently more resilient than bellows for higher backpressures and rapid cycling applications. Upgrading to a Balanced Diaphragm therefore lowers maintenance costs, improves reliability and increases stability.

The second technology, Bellows Leak Detection, addresses the problem of bellows failures, which are challenging to detect and often remain unnoticed for years until removal of the valve for periodic service. Leak detection and repair (LDAR) programmes may include PRVs, but their target sources for leakage detection are flanges or valve seats, so bellows ruptures will generate fugitive emissions through the PRV bonnet vent that may not be in the LDAR scope. In addition, PRV installations are often difficult to access and in hazardous locations, making leak detection difficult.

The Bellows Leak Detection solution is a safer and more efficient method for detecting bellows failures and emissions. It consists of a back-up piston and a Rosemount™ wireless or wired pressure transmitter. The back-up piston can reduce emissions by over 90% in the event of a bellows rupture because it has a much smaller clearance than a standard bonnet vent, and it ensures balanced operation. The pressure transmitter provides instant timestamped notification of bellows failure and emissions volume data in real-time.

Upgrade kits for existing Crosby J-Series PRVs are available for both new technologies, and new PRVs can be purchased with these features pre-installed.

Valve system with OPC UA.

Emerson's AVENTICS™ Series Advanced Valve (AV) valve system with Advanced Electronic System (AES) Profinet and Ethernet/IP is now available with preinstalled Open Platform Communications Unified Architecture (OPC UA)* functionality, making it the first and only valve system to offer this directly integrated capability. The AES helps users solve interoperability challenges and access data more easily while the integration of the digital twin can improve productivity and efficiency.

“The AVENTICS Series AV System with OPC UA is a notable leap forward in the flexibility and integration of valve systems because it makes the transition to IIoT significantly simpler for engineers,” said Nils Beckmann, senior manager of product marketing, IIoT at Emerson. “With OPC UA, engineers don’t need to change a whole system or architecture to access valve data. They now have the flexibility to continue using their own cloud systems and software to gain easy access to data and analytics without disrupting or modifying the PLC.”
 

A valve system with integrated OPC UA functionality simplifies communication with upper systems since data and analytics are received via the valve system and communicated directly to upper systems, no gateway necessary unless deeper analysis or local dashboards are required. This can result in costs savings for users since it’s more complex and expensive to receive analytics from a valve system without OPC UA.

OPC UA functionality also expands the connected capabilities of the valve system itself, making it easier for users in industries such as automotive, food and beverage, packaging, pulp and paper industries and more to digitally transform. When organizations undergo digital transformation, key protocols such as OPC UA embedded in technologies enable device monitoring and machine connectivity when sending data from a valve system to an upper system. The AES is simple to integrate and connect to new or existing applications and machines and provides easy access to data and analytics without changing the programmable logic controller (PLC).

Valve technology dramatically reduces energy consumption.

Festo has developed piezo valve technology for gas handling that simplifies the replacement of traditional solenoid valves, facilitates integration and can reduce energy consumption by as much as 95%.

Extremely low energy consumption, coupled with silent, no-heat operation, makes piezo valve technology particularly attractive for laboratory and medical device applications. Low noise is prized for bedside medical instruments and devices and is also desired in the laboratories where a lot of instruments may be deployed. However, it has not been possible to simply replace standard magnetic solenoid valves with piezo technology because they operate very differently (see box-out). For example, most of today's control solenoid valves are designed to operate at a voltage between 5 and 24V, whilst a piezo valve requires 310V and special control electronics.

The benefits of piezo technology
The principle of piezo technology is quite different from that of a traditional, wound coil solenoid valve. The core element is the piezo ceramic bender. When this is electrically charged, it creates a polarisation within the crystalline structure that causes the ceramic material to bend. The bending is proportional to the applied voltage. By mounting the bender over a nozzle it enables the flow rate or pressure to be regulated proportionally. The higher the voltage, the greater the bender distortion and flow rate.

Solenoid valve coils require the electric power to be applied for the coil to remain actuated, whereas a piezo valve behaves like a capacitor. It only requires an initial current to energise the ceramic element and then the current consumption practically drops to zero, yet the ceramic bender will retain its shape until it is discharged or further energised.

In a piezo valve there can be one or two ceramic benders – and above each of these is a spring, which provides the return action. A single 2/2-way valve is a very easy way of controlling a flow rate. It has one bender and two ports. The higher the applied voltage, the further it opens. A 3/3-way valve function has three ports and utilises two benders. A complete pressure regulation system can be set up with this compact solution. It uses one bender for pressurisation (or increasing the pressure) and the second one for exhausting (or reducing the pressure). A third state to maintain the pressure is achieved by closing both benders, blocking the flow and pressure.

To overcome this potential barrier to adoption, Festo has developed piezo technology that enables piezo valves to be easily integrated into systems architectures using a standard 12 to 24V supply. Historically, consistent manufacture of piezo valves has been difficult. They assure reliability by producing piezo cartridges that can be incorporated into the various components on fully automated, high output production machinery. The cartridges consist of the fragile ceramic bender mounted within a housing incorporating the injection-moulded port nozzles. The gas flows in or out through these nozzles.

Their VAVE-P piezo valve incorporates everything needed for easy actuation. The VAVE-P is operated as normal with 12 to 24V and generates the required piezo voltage internally. It includes simple, open-loop actuation electronics, 310V voltage generation and a 2-channel piezo driver stage with current limitation. The two-channel electronics in the VAVE-P makes it possible to actuate two valves for regulating the flow rate passing through the valve or a 3/3-way valve function for regulating the pressure, using separate piezo valves for pressurisation and exhausting. This 3/3 way option is a very easy way of controlling pressure and is unique to piezo technology. The interface for the VAVE-P is always the same: two analogue inputs and the flexible power supply of 12 to 24V. There is no easier way to replace a proportional solenoid valve.

Using their piezo technology, it is easy to set up a complete flow rate and pressure regulation system. Another example is the compact VEMD flow control valve combining a piezo valve, flow sensor and control electronics. This allows you to achieve a linear ratio between input voltage and output flow rate. Its counterpart for regulating pressure is the VEAB proportional pressure regulator. This is equipped with two piezo valves, again each with one piezo bender for pressurisation and one for exhausting, plus the necessary electronics and a pressure sensor. The VEAB therefore provides a complete closed-loop pressure control solution in the smallest installation space.

The ability to purchase piezo valves as standard off-the-shelf components which are simple to integrate is opening up applications and uptake within laboratory instruments and medical devices applications. For specialist applications, Festo provides an application engineering and design support service.

Valve for heavy slurry service.

Emerson’s Clarkson™ KS1 Knife Gate Valve is a true bi-directional, full bore, ASME Class 150 valve designed for the rigours of heavy slurry service. Its advanced, patented sealing system delivers zero-leakage isolation for longer, enabling increased run time and throughput.

The new Clarkson KS1 Knife Gate Valve, designed to help mine, oil sands and pulp & paper operators achieve increased availability of their most challenging slurry processes has been announced by Emerson.

“The Clarkson KS1 is a compelling innovation for operators of heavy slurry processes, such as tailings lines,” explained Mike Gordon, director of Emerson’s knife gate valve business. “This valve is purpose-built for extended zero leakage isolation in these tough environments, so these processes run uninterrupted for longer to improve throughput and minimise valve maintenance costs.”

The new knife gate valve features a patented gate edge seal design that creates a continuous seal around the gate, together with a precision-moulded elastomer seat. This heavy-duty seat increases the contact area and resilient sealing ability of the valve compared to standard O-ring designs, resulting in superior isolation performance over an extended lifecycle.

The valve design has been optimised to thrive in heavy slurry conditions with a full round port that eliminates protrusions into the flow, which minimises turbulence across the valve and reduces wear on valve components and downstream equipment. Reversible, rotatable wear rings also come standard on both sides of the valve to protect the seat and extend maintenance intervals.

Maintenance teams were also top of mind during the design of the KS1. The valve is repairable with standard tools and readily available spare parts. Adjustments can be made to the packing system externally that dynamically self-adjust pressure to the gate edge seal system. The KS1 is also designed to standard MSS SP-135 face-to-face dimensions for simple changeout and upgrade of underperforming installed valves.

The Clarkson KS1 comes built tough for the rigours of severe slurry service in sizes 2” through 30” with a variety of available flange patterns, an ASME Class 150 pressure rating of 290 psi (20 bar) at ambient temperature and a temperature rating up to 300°F (149°C). Alternate materials are also available to combat extraordinary abrasive and corrosive process conditions and a variety of automation options can be configured to suit.

Shutoff valve.

WIKA's new monoblock with flange connection has been designed for applications in the process industry. The compact design integrates a shut-off valve to separate the process from the instrument side.

 

The one-piece construction and the double sealing (metal and plastic), tested in accordance with BS6755 / ISO 5208 leakage rate A, give the compact instrument the greatest possible safety. Its high-quality manufacture ensures smooth handling, even at high process pressures. 

The model IBF1 can be fitted with either a ball valve or needle valve. The new instrumentation valve complements the existing monoblock portfolio which includes the models IBF2 (block & bleed) and IBF3 (double block & bleed). 

WIKA supplies a customer-specific assembly of measuring instrument and monoblock (“instrument hook-up”), ready for operation and leak-tested on request. All IBF models can also be fitted on level indicators and differential pressure measuring instruments for level measurement.

Valve for transport innovation... and what a valve!

“This is science and innovation at work.  I applaud HyperloopTT and GNB for not just imagining the future but  going out and making it a reality.” Dr Ami Bera, US Congressman for California

Hyperloop Transportation Technologies (HyperloopTT) have revealed their safety isolation valves today, critical safety components for HyperloopTT systems. Built to precise specifications by GNB KL Group in Elk Grove, (CA USA), the valves will isolate sections of hyperloop system tubes to allow for easier system pressurization for maintenance or emergency. 

The full-scale valve is built for commercial operations measuring 16.5 feet in height, weighing 77,000 pounds, and can withstand 288,000 pounds  (14.7 PSI) of force. The values can fully open or close within 30 seconds. 

In most emergency scenarios, capsules will stop at pre-determined emergency stations along the route’s length to exit the capsule and tube infrastructure. As a redundant emergency response option, the HyperloopTT system will isolate sections of the tube for re-pressurization. If the capsule is unable to stop at a pre-defined exit, a lit emergency path in the depressurized tube will lead passengers to emergency hatches to safely exit the infrastructure.

GNB began collaborating with HyperloopTT engineers in 2019. Now complete, the valves will be shipped to the HyperloopTT facility in Toulouse, France, for integration and certification.

“One of the questions we regularly receive regarding our technology is about safety, especially in emergency scenarios,” said Andres De Leon, CEO of HyperloopTT. “These valves, built to safety certification standards by a world-class leader, are an essential part of hyperloop safety, as they allow us to isolate portions of the track in the event maintenance is needed or in the rare case of an emergency.”

“Working with HyperloopTT has allowed us to showcase our world-class abilities with vacuum parts and technology,” said Ken Harrison, president of GNB. “ We specialize in building specialty valves and chambers for fusion reactors, government science labs, and more, so HyperloopTT’s groundbreaking transportation system is a perfect project for us.”

HyperloopTT’s European Research and Development Center is in Toulouse (F), the aerospace capital of Europe, is home to the world’s first and only full-scale test system.

High precision control of fluids and gases.

Festo has introduced the VYKA range of media separated solenoid valves offering high precision control of virtually any fluid or gas. Just 7mm in width and with an orifice size of 1.2mm, the VYKA range has a class leading pressure-to-orifice size ratio and offers a compact solution to a wide variety of dosing and continuous flow applications.

Suitable for use as dosing valves for contactless dispensing or as control valves for continuous flow applications, the VYKA range owes its excellent chemical resistance to the fact it is constructed from inert materials. Separating diaphragms made of high-performance FKM and FFKM polymers mean that the valves can be used safely with very aggressive media, providing protection whilst simultaneously preventing corrosion. This makes them an excellent choice for electronics and semiconductor manufacturing, including wafer production and deposition, as well as printing applications.

Pharmaceuticals, medtech and food manufacturing will also benefit from the control accuracy and compact size of VYKA valves. Uniquely, the valves’ wetted materials are FDA listed and their low internal volume makes them very easy to clean: a real boon in reducing valuable media losses, or for sensitive and hygienic environments. Typical applications include liquids handling in laboratory automation, in-vitro diagnostics and high-precision filling applications with sensitive and aggressive media (such as perfumes and aromatics, or packaging contact lenses). 

Pressures of up to 4 bar and a flow rate of up to 350 ml/min are not a problem for VYKA solenoid valves. They utilise current control, which significantly improves the reproducibility of the switching behaviour critical to delivering highly accurate results. When a VYKA valve is used in conjunction with compatible Festo connectors and controllers, a holding current reduction from 0.3W down to 0.06W can be achieved, reducing heat build-up and preventing thermal transfer to sensitive media passing through the valve.

The VYKA range is extremely flexible thanks to its 3/2, 2/2 (NC/NO) variants. Festo also offers a powerful range of accessories, greatly extending the performance and capabilities of the VYKA range. These include a variety of electrical connection options through the VAVE electrical connection box with integrated holding current reduction. The VAEM valve control module for up to eight valves enables even higher dispensing precision by accurately controlling pulse durations down to 2ms repeatability. The range is completed with NLFA liquid compatible fittings, VAVN dosing nozzles and the VABS PEEK material connection module – so that machine builders and OEMs can source everything they require to meet demanding end-user specifications.

Check valve.

The new model CV check valve from WIKA is designed for a wide range of applications in the process industry. Its sealing system with a self-centering piston reliably prevents backflow of liquid and gaseous media.

The reliability of the new instrumentation valve is mainly due to its redundant sealing, consisting of an O-ring and a metal cone. Its leak tightness has been tested in accordance with BS6755/ISO 5208 leakage rate A. The solid-machined, robust design of the model CV ensures high repeatability and a long service life, even in heavy-duty applications. The pressurized parts correspond to the safety factor of 4:1.

For the new check valve, WIKA offers an application-specific assembly with a measuring instrument. Such an instrument hook-up is delivered ready-to-install and leak tested.
