Hi!
Cracking Pressure - Differential Pressure at which valve opens and flow occurs.
0.00 PSI - is a special design check valve for use on the inlet side of the PMPT & PMPNT Pumps used for increasing fill rate of pump.
WSSCV Check Valve
The Model WSSCV is an all stainless steel in-line check valve for steam, gas, or liquid service. It provides tight shut-off, minimizes water hammer and also stops recycling of pumps by preventing back flow of liquid. Used in the petrochemical, pulp & paper, textile and food & beverage industries. The WSSCV all stainless steel check valves will operate much longer and are less problematic than bronze or cast iron check valves.
