The valve's injection molded Kynar® unpigmented polyvinylidene fluoride (PVDF) construction with FKM O-ring is ideal for use with ultra-pure water, deionized/distilled and demineralized water systems, clean chemical processes, electronics, pharmaceutical operations and food processing.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. Chemtrol® Kynar® natural PVDF exhibits superior strength, working temperature and chemical resistance characteristics. 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. Choose Chemtrol® valves for the most reliable, versatile and economical valve option in commercial and industrial applications.Features:Valve pressure rating 150 psi at 73°F water non-shock full-portMaximum service temperature 280°FFull portTrue Bloc® designFKM O-ringFemale thermo-seal socket fusion connectionsBlack handleDo not use or test with compressed air or other gasesASTM D3222 Type I material.
