This Chemtrol True Union ball check valve stops the flow of media in one direction while allowing flow in the opposite direction, with minimum turbulence and chatter while maintaining pump prime. The valve's injection molded PVC construction with EPDM O-ring is ideal for use in chemical processing, industrial plating, chilled water distribution, chemical drainage and irrigation systems. The original Chemtrol True Union design allows the valve and operational components to be conveniently lifted from the piping system for repair or replacement. The valve can be easily joined with the flanged end connections. Please refer to Chemtrol technical data sheets, chemical resistance guides and catalogs for engineering and installation information. PVC Schedule 80 exhibits excellent corrosion resistance properties and has the highest long-term hydrostatic strength of any other major thermoplastic material used for piping systems. Chemtrol PVC valves are lightweight, easy to install, maintenance-free, and will not rust, scale, pit or corrode. Choose Chemtrol valves for the most reliable, versatile and economical valve option in commercial and industrial applications. Chemtrol ball check valves are backed by a 1-year limited warranty. Because Chemtrol is a NIBCO brand the flow-control valves are unsurpassed in quality, performance and longevity.
