A Rising Stem Ball Valve is being added Trillium Flow's to its extensive Red Point® production catalogue of ball, check, double block and bleed, gate, and globe valves. This latest innovation is designed to reduce friction on moving components, extend maximum service life, and provide a low-maintenance design. The Rising Stem Ball Valve is widely used in the oil and gas industry, where its robust design and reliability in preventing leakage are valued.
The new valve’s friction-free sealing and non-contact ball movement achieve longer potential service life and, combined with the single-seated design, features a broad operating temperature range from -196°C to 450°C. The impact of thermal expansion has been minimized by the configuration of the valve components, allowing for this impressive temperature range.
This newest model is suitable for dirty service with a uniquely designed bottom trunnion that ensures the prevention of solid particle ingress into the valve.
The distinct quarter-turn helix-shaped stem mechanism design is fully enclosed within the valve body, providing additional protection against environmental factors and eliminating the requirement for frequent lubrication. When closing the valve, the downward linear movement of the helix passing through the roller bars on the top of the ball causes the ball to rotate 90 degrees without physical contact, ensuring friction-free operation.
Regular ball and pin assembly designs often suffer from potential welding-related cracking issues. The new RSBV design eliminates this by employing an innovative weld-free design, enhancing its reliability and longevity. Additionally, we have addressed further weld cracking and thermal expansion concerns arising from the use of different metals with a non-shrink fitted/welded seat design.
The extensively tested Outside Screw and Yoke design is renowned for its reliability and lightweight construction, making it a preferred choice for operations worldwide. As always with Red Point designs, valves are made according to the best fit solution based on each customer’s specifications. The new RSBV design is no exception and comes in a wide range of materials, depending on what’s most appropriate.
Targeting applications where the demand is for a long-serving and reliable valve, Red Point’s latest offering is testament to its heritage of finding innovative and effective engineering solutions to the industry’s problems. As part of Trillium Flow Technologies’ commitment to excellence, the new design is a great example of our ability to bring new ideas to old problems and put forward simple but effective solutions with top-tier products and services.
