These "Extra Heavy Duty" check valves have a one-piece construction and are molded from Rigid PVC to provide superior tensile strength. With a robust stainless steel poppet and hardware, the stainless steel spring closes the valve against pressure, eliminating flow reversal and minimizing hydraulic shock. The stemless acetal poppet guide provides long-lasting, quiet, trouble-free operation in vertical and horizontal installations, while the flow diverter minimizes turbulence and friction loss.
