This 3″ Sch 80 CPVC True Union Ball Valve, VITON, (SOC x FNPT) is a true union ball valve open and closes a ball inside with a full sized hole with a quarter turn of the handle. The integrated unions allow the valve to be easily installed or removed. One side connects to a pipe using solvent welding and the other has female threads. CPVC is a higher temperature version of PVC and has better chemical resistances. VITON seals provide increased temperature resistance than EPDM seals and recommended for exposure to oils, gasoline and aggressive chemicals.
