Available elastomers include Buna N, EPDM, Viton, Silicon and Teflon. Valve internal components can be customized to fit your exact application requirements.
Full Port, Lowest Pressure Drop. Full Port Wafer Check Valves provide more flow and lower pressure drops than conventional check valves. Our elastomer hinge check valve design takes performance to an entirely new level by eliminating the restrictive valve seat and substantially increasing the valve’s open area and flow coefficient (Cv). They are ideal for application in vacuum pumps, compressed air and gas systems as well as in water systems where low head loss and elimination of water hammer are desirable.


 Features:
1. Light weight,versatile design— 80% to 90% less than conventional full-body swing check valves
Simplifies piping
Reduces thermal and seismic considerations
Optimizes space utilization
Lowers installation costs
Reduces pipe supports
Requires less number of man-hours
2. Single Disc opening
