NIBCO, MC912AC, F61TB-V, Ball Valve - Model C, Flanged, Tru-Bloc® True Union, Black PP, FKM, 1-1/2"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's injection molded polypropylene construction with FKM O-ring is ideal for use with hot corrosive liquids, chemical processing, industrial plating, laboratory and industrial waste drainage systems, and waste treatment systems.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. Chemtrol industrial thermoplastic flow-control systems perform well in harsh environments because they are made with materials that are resistant to abrasion, corrosion, weather, chemical and biological attack. Chemtrol black polypropylene demonstrates excellent tensile strength, UV stability and versatile chemical resistance properties, making it the material of choice for harsh industrial, outdoor and underground applications. 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-shockFull portMaximum service temperature 180°FTrue Bloc® designFKM O-ringFlanged end connections compatible with ANSI B16.5 Class 150Red handleDo not use or test with compressed air or other gasesASTM D4101 material.
