CPVC Check Valve

The CPVC Check Valve is engineered to prevent backflow in demanding corrosive and industrial fluid systems. By allowing flow in only one direction, it protects pumps, pipelines, and downstream equipment from reverse flow damage, contamination, and pressure surges. Its reliable one-way sealing action makes it an essential component in chemical processing, water treatment, and industrial fluid handling applications.

Constructed entirely from Chlorinated Polyvinyl Chloride (CPVC), both the valve body and internal trim deliver outstanding resistance to a broad spectrum of aggressive media. CPVC's inherent chemical inertness and elevated temperature tolerance make it far superior to standard PVC and many metallic alternatives in environments where corrosion is a primary concern. The all-plastic wetted path eliminates the risk of metal ion contamination, ensuring fluid purity throughout the system.

Available in both ball check and swing check configurations, this valve accommodates a wide range of flow conditions and installation requirements. End connections are offered in socket (solvent weld) or threaded (NPT) styles, providing flexibility for integration into new or existing piping systems. The size range spans 1/2" through 4", covering the majority of industrial and commercial piping applications.

This check valve exhibits exceptional resistance to acids, alkalis, and chlorinated water, making it well suited for chemical dosing lines, swimming pool and water treatment systems, plating operations, and semiconductor manufacturing. Its resistance to oxidizing agents and many organic solvents further broadens its applicability across diverse industrial sectors.

Manufactured in compliance with ASTM D1784, the CPVC material meets rigorous standards for cell classification, ensuring consistent mechanical properties, dimensional accuracy, and long-term durability. This compliance provides engineers and specifiers with confidence in material quality and system reliability over the full service life of the installation.
