NIBCO, MA781A6, S45M3-V, Ball Valve - Socket, True Union, 3-Way 3-Position Multi-Port, PVC Schedule 80, FKM, 1/2'The Chemtrol® True Union three-way, three-position multi-port ball valve is ideal for applications where flow diversion and on/off control is needed. The valve may also be used to alternately divert flow from either of the side run inlet ports to the branch center inlet port. The full port design produces minimum flow restriction with the lowest possible pressure drop for 90-degree porting. The valve's injection molded PVC construction with FKM O-ring is ideal for use in chemical processing, industrial plating, chilled water distribution, chemical drainage and irrigation 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. No disruption or length change of connected piping is required. The valve can be easily joined with the socket end connections. 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.Features:Valve pressure rating 150 psi at 73°F water non-shock full-portMaximum service temperature 140°FTrue Union designMulti-portFKM O-ringSocket end connectionsOrange handleDo not use or test with compressed air or other gasesASTM F1970NSF/ANSI Standard 14NSF/ANSI Standard 61, Annex G.
