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 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® 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.
