CPVC Foot Valve

A CPVC foot valve is a non-metallic, corrosion-proof non-return valve integrated with an inlet strainer mesh screen, manufactured from Chlorinated Polyvinyl Chloride (CPVC) for installation at the bottom suction point of liquid pumping systems. The CPVC material offers broad chemical immunity to acids, bases, and salts at elevated temperatures up to 93°C, while the internal check mechanism holds liquid in the suction line to prevent pump unpriming and the strainer screen excludes destructive particulate debris. Conforming to standards like ASTM F1970 and NSF/ANSI 61, these chemical-grade plastic valves are primary specifications in chemical dosing wells, industrial plating lines, and corrosive wastewater sumps, allowing process engineers to maintain continuous pump priming by importing certified CPVC foot valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
