The 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 CPVC construction with EPDM O-ring is ideal for use in systems for hot corrosive liquids, hot and cold water distribution, chemical processing, industrial plating, deionized water lines, chemical drainage, waste water treatment systems, and similar applications above the temperature range of PVC.

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. Corzan® CPVC Schedule 80 thermoplastics demonstrate excellent mechanical strength over broad temperature range, outstanding underground performance and superior hydraulics. Chemtrol Corzan® CPVC 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.
