NIBCO® Chemtrol® Heavy Duty Tru-Bloc® TruUnion Ball Valves

The double union design of these valves permits in-line maintenance without disconnecting pipe. With a full port design, the Cv can be disregarded since pressure drop through valve is equivalent to same length of schedule 80 pipe. Applications: chemical processing, plating, photo processing, laboratories, water conditioning, electric production, pharmaceutical and more.

  • PVC or CPVC
