RSK - Swing-check Main Feedwater and Bypass Feedwater Isolation Valve
Main and bypass feed-water isolation valve with low pressure loss, spherically guided plate, and stable performance.
Ensures minimal pressure loss, improving overall plant efficiency and operational performance.
Spherically guided closing plate enhances stability and prevents magnetite build-up for reliable operation.
Customisable with solenoid-operated pilot valves for optimised low-flow performance.
The RSK Swing-Check Gate Valve ensures efficient isolation in main and bypass feed-water applications. Designed to be actuated by the system’s medium, it offers reliable performance with minimal pressure loss, enhancing power plant efficiency. The valve is available in forged or cast carbon and stainless steel, with sizes up to 29.9” (760mm) and Class ratings up to 1500. A spherically guided closing plate enhances stability, and special designs with solenoid-operated pilot valves are available for low-flow applications. The robust construction prevents sensitivity to magnetite build-up, making it a durable and efficient choice for demanding isolation applications.
