- The Chemtrol® Tru-Bloc True Union ball valve is engineered with a self-adjusting seat and upstream and downstream blocking capability to stop flow when an alternate union is removed for servicing the piping system. The valve 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. 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 SCH 80/XH thermoplastics demonstrate excellent mechanical strength over broad temperature range, outstanding underground performance and superior hydraulics.
