This 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's injection molded red Kynar polyvinylidene fluoride (PVDF) construction with FKM O-ring is ideal for use with hot corrosive liquids, chemical processing, industrial plating, waste treatment systems and outdoor installations. 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. Chemtrol Kynar red PVDF exhibits superior strength, working temperature and chemical resistance characteristics. Red pigment provides UV protection. Kynar PVDF offers versatile chemical resistance to slats, strong acids, dilute bases and many organic solvents such as aromatics, aliphadics and chlorinated groups. PVDF is also ideally suited for handling wet or dry chlorine bromine and other halogens.
