Wafer Check Valves
Asahi/America, Inc. (Malden, MA) has introduced 10- and 12-inch PVC wafer check valves. 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. The wafer check valves are easily installed by slip-fitting the valve between two mating flanges. The unique design of the disc and stopper permits the disc to fully open when upstream flow is present, without interfering with schedule piping and mating flanges.
