Product Overview
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.
Features
• 316 Stainless Steel Body and Internals
• Low cracking pressure on spring (1/4 PSI) to minimize resistance and maximize flow.
• Available with optional 5 PSI cracking pressure (must specify at time of order)
• Available with NPT, SW, or optional Flanged connections
• Spring made from Inconel-X-750 to handle extreme temperature as well as corrosive applications
• Body is seam-welded to eliminate O-rings or gasket seals which can be affected by high temperature steam or hot condensate
• Spring assisted closing of check valve to minimize noise and wear
Selection / Sizing / Capacities

Please select model base on Cracking Pressure (PSI) in below tables

1. NPT connection type.
   
* Differential Pressure at which valve opens and flow occurs.
† WSSCVQF is a special design check valve for use on the inlet side of the PMPT & PMPNT Pumps. It is center-guided and contains no spring . Used for increasing fill rate of pump.

 2. Socket Weld (SW) connection type.
  
* Differential Pressure at which valve opens and flow occurs.
