These ball check valves stop the media flow in one direction while allowing flow in the opposite direction, with minimum turbulence and chatter, while maintaining pump prime. The valve's injection-molded polypropylene construction, with either an EPDM or FKM O-ring, is ideal for hot corrosive liquids, chemical processing, industrial plating, laboratory and industrial waste drainage, 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. The black polypropylene material demonstrates excellent tensile strength, UV stability, and versatile chemical resistance properties, making it the material of choice for harsh industrial, outdoor, and underground applications.
