- Wafer Check Valves are available in diverse designs: Solid Body, H-Body, and Extended Body, catering to sizes up to 30 inches. They are constructed from premium materials including Carbon Steel, 316 Stainless Steel, Cast Iron, Brass, and Aluminum. Our valves come with a variety of elastomers such as Buna N, EPDM, Silicon, and PTFE. Valve internal components can be customized to meet specific application requirements.
- Full Port Design, Ensuring Minimal Pressure Drop.Our Full Port Wafer Check Valves are engineered to provide maximum flow with minimal pressure drops, surpassing conventional check valves. The innovative elastomer hinge check valve design eradicates the restrictive valve seat, significantly amplifying the valve's open area and flow coefficient (Cv). They are perfect for vacuum pumps, compressed air and gas systems, and water systems where low head loss and prevention of water hammer are crucial.'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.
