® ® Product Guide—Ball Valves www.nibco.com www.nibco.com True Union Ball Valves — A Family of Products The True Union feature, an exclusive Chemtrol® introduction, so revolutionized the industrial plastic valve industry that it has become the standard followed by all major manufacturers. The purpose of the design is to permit the valve cartridge, i.e., the body containing all operational components, to be easily lifted from the piping system for servicing/replacement when the union nuts are backed off. Easy repair/replacement, interchangeability, distribution availability, technical...

® Product Guide—Ball Valves www.nibco.com PVC and CPVC Tru-Bloc® Ball Valves, True Union Model D 1/2" through 2" Nominal Sizes 250 psi at 73°F water– non-shock– full port As a result of continuous testing and improvements since the inception of the True Union Ball Valve, three distinct model changes have occurred. The original True Union Model A design had a seat-carrier that slid into the smooth bore of the valve body, held in place by the external nut and end connector. Tightening the external nut adjusted the compression of the PTFE seat onto the ball. The first major evolution to the...

® Product Guide—Ball Valves www.nibco.com PVC and CPVC Bleach Ball Valves True Union Model C The Problem Sodium hypochlorite, used in water treatment, aquatic centers, and paper and textile applications, can become trapped in the body cavity of a closed ball valve and create failure conditions as the unstable chemical decomposes. The Chemtrol® Solution The Bleach Ball Valve is a special factory modification to a PVC or CPVC True Union Model C Ball Valve that effectively vents sodium hypochlorite out-gassing to the pressure port. In addition, the inner valve surfaces are kept constantly...

Flow can be blocked at this port while adjacent piping is disconnected for repair or alteration. • ADJ externally molded onto the body to indicate the open end used for assembly. Adjustment of this union nut can compensate for wear of PTFE seats, with no production loss to remove valve for internal adjustment. •Valves are manufactured and assembled without exposure to silicone compounds. •Full port design produces minimum flow restriction with the lowest...

® Product Guide—Ball Valves Installation and Maintenance Instructions True Union Style Ball Valves Tru-Bloc® – True Union Multiport – 3-Way/3-Position Diverter – 3-Way/2-Position Installation Chemtrol® Union-End Ball Valves can be fitted with socket, threaded, or flanged end connections. When joining union-end valves, or when flanging end connectors, never make the joint to the end connectors while they are attached to the valve body. Remove the union nuts and end connectors from the valve cartridge first. In order to prevent mishaps with the union nut, slide it (smallest bore first) over...
