PVC Wafer Check Valves
Asahi/America, Inc. (Malden, MA) has expanded its offering of PVC wafer check valves to include sizes 4, 6, and 8 inches. Wafer check valves are installed on the discharge side of pumps to prevent back-flow flooding that could seriously damage pump systems. Asahi’s new wafer check valve’s body, disc, and stopper assembly are machined from solid PVC plate stock, which conforms to ASTM D1784 Cell Classification 12454A, says the company. This material was selected based on its excellent chemical resistance and mechanical properties. The wafer check valve conforms to ISO 5752 face-to-face dimensions and can be easily installed by slip-fitting the valve between two mating flanges.
