Valves - Asahi/America wafer check valve

PVC wafer check valves from Asahi/America are installed on the discharge side of pumps in applications such as aquariums, water attractions, water treatment and municipalities to prevent backflow flooding that could seriously damage pump systems. The wafer check valve’s body, disc and stopper assembly are machined from solid PVC plate stock, which conforms to ASTM D1784 Cell Classification 12454A. They conform to ISO 5752 face-to-face dimensions and are easily installed by slip-fitting the valve between two mating flanges. Valves are available in PVC, 3 through 12 inches, with EPDM seals and no spring, standard. The 3- to 8-inch valves operate at a maximum pressure of 150 psi; with 10- and 12-inch valves at 90 psi and up to 120 degrees F. Optional seals in FKM and an ETFE-coated stainless steel spring are available. 800/343-3618;
