Dual plate wafer check valve
Dual Plate Wafer Check Valve
Introduction of Dual Plate Wafer Check Valve
Dual plate, spring loaded, wafer style design for the protection of gas or liquid piping systems
Industry Standards: ASME B16.1, B16.5, B16.24, B16.34, B16.47 and B31.1
- Light weight, versatile design, 80 to 90% lighter than conventional full-body check valves.
- Reduces pipe supports, simplifies piping, easier, less costly installation.
- Reduced thermal and seismic considerations.
- No need for additional expensive support.
- Optimum space utilization; simplified piping.
- Spring-loaded, double door design has low cracking pressure.
- Discs open 85° to ensure positive closing.
- Materials and trims available for all services within temperature range.
- Extended leg springs prevent seat wear caused by scrubbing.
- Springs are precisely calculated to increase the responsiveness of the disc, thus reducing damaging effects of water hammer.
- Resilient or metal-to-metal seat available.
- BUNA-N, Viton®, EPDM (and other materials as required) molded into the body.
