Isolation product lines acquired!

Humphrey Products has recently acquired “Medical and Media Isolation Product Lines” from the Curtiss-Wright Corporation. Specifically, these products include Liquid Isolation (Inert) Valves, Liquid Isolation (Inert) Proportional Valves, and a high resolution Proportional Control Valve Series for air, inert gases and some liquids.

Humphrey is in the process of moving the production lines, inventory and jobs from Nogales, Mexico, back to America and plans to begin marketing these products under the Humphrey brand in the September/October time period.

Founded in 1901, Humphrey Products is a leading producer of pneumatic products, including valves and cylinders, and design and manufacturing of specialty custom Engineered Products. Humphrey’s products are proudly made in the USA and used in a variety of applications in medical, process control, manufacturing automation, transportation, analytical instrumentation, packaging and material handling.

Explosion proof linear actuator. #PAuto @ExlarActuators

The Exlar® linear actuator line from Curtiss-Wright Corporation, has been expanded to include the EL120 explosion-proof linear actuators.

Their EL120 linear actuator meets ATEX requirements for use in potentially explosive atmospheres and are in conformity with the EU ATEX Directive 94/9/EC as well as the IECEx Scheme. Additionally, it is rated for Class I, Div 1, Groups B, C, D, and T4 hazardous environments.

Features include
• Speeds up to 37.5 ips (950mm/s)
• Forces up to 4000 lbs (17kN)
• Strokes up to 18 inches
• Feedback configurations for nearly any servo amplifier
• Several mounting configurations
• Windings available from 24 VDC to 460 VRMS
• Completely sealed motor assures trouble-free operation
• ATEX Ex d IIB +H2 T4 Gb
• IP66
• CSA Class I, Div 1, Group B, C, D, and T4 hazardous environment rating
• IECEx CSA 14.0014X
Applications
• Valve control
• Damper control
• Gas turbine control
• Printing presses
• Engine test stands
• Fuel skids
• Paint booths
• Shipboard fuel management

The EL Series of linear actuators integrate a highly efficient planetary roller screw mechanism with a high torque servomotor in a single self-contained package. This highly robust design is engineered to provide reliable and precise operation over thousands of hours, handling heavy loads—even under arduous conditions.

These servo-electromechanical systems offer a clean, fast, simple, and cost effective replacement for hydraulic actuation and longer life alternative to pneumatic actuation. Superior servo-electric actuator reduces emissions, minimizes energy consumption (80% system energy efficiency), increased position control and accuracy – all leading to lower cost.

For process applications, the EL120 offers a unique combination of high speed, performance, and accuracy. High performance is achieved with respect to speed, linearity, load sensitivity, deadband, and temperature range. For gas turbines with variable guide vanes, the EL120 actuators provide precise positioning and feedback for fine tuning injector airflow to maintain CO and NOx emissions. In oil and gas applications, the EL120 effectively managed pressure drilling choke valves or any valve application that requires extremely fast response to the smallest command signal changes without overshoot, even when friction is present.

The Exlar EL Series provide, a superior and cost-effective solution even in the most severe and demanding environments.

Electric rod style linear actuator!

The FT Series roller screw driven actuators from Curtis Wright, offer high thrust, high speed, and high robustness in a compact form factor, making them an ideal alternative to hydraulic cylinders. With continuous force rating to 40,000 lbf (178 kN), speed to 60 in/sec (1,500mm/sec) and stroke lengths from 6 inches (150mm) to 8 feet (2,400mm) the FT Series can be applied across a wide range of linear motion applications.

The new FT45 has a continuous force rating of 10,000 lbf (44.5 kN), filling the gap between the existing FT35 and FT60 models. The FT45 features the following key enhancements over the existing FT Series frame size designs, including the largest FT80 model:

• IP65 (min.) environmental protection standard on all mounting configurations
• Idler pulley design greatly simplifies motor installation and belt tensioning / maintenance
• Grease zerk fitting allows re-greasing of nut assembly without having to disassemble the unit
• Removable front seal bushing design greatly simplifies front seal maintenance / replacement
