The original Chemtrol® True Union design allows the valve and operational components to be conveniently lifted from the piping system for repair or replacement. Tru-Bloc® advances the True Union concept with the self-adjusting energizer O-ring. The valve can be easily joined with the socket 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 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.
