MADE IN AMERICA


​​​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.
