Oil-Controlled Closure Swing Check Valve 

​​​The Oil-Controlled Closure Swing Check Valve is a free opening check valve with two-stage closure to minimize slam and surge on high head water and sewage pumping applications.  The valve is designed to freely and smoothly open on pump start-up and provide full waterway for minimum head loss.  Following pump shutdown, the valve closes rapidly during the first stage then engages the hydraulic system to provide a controlled final closing speed to prevent slam and mitigate surge.


​MADE IN AMERICA

Available from 2” to 54”, ANSI Class 125 or 250 flanged for horizontal or vertical installation, its lead-free, heavy-duty construction.
