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 PVC construction with FKM 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 universal socket and threaded end connections. 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. Chemtrol 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.
