2. Defining the CPVC True Union Floating Ball Valve
The CPVC True union floating ball valve is a high-integrity, quarter-turn valve engineered for isolating or regulating fluids within aggressive chemical, water, or waste pipelines. "True union" indicates fully demountable endpoints via union nuts enabling rapid valve replacement or maintenance without disturbing pipework. "Floating ball" refers to a ball design that, under pressure, presses against the downstream seat to achieve bubble-tight closure, minimizing internal leakage.
Key structural features:
- Body Material: Chlorinated Polyvinyl Chloride (CPVC), renowned for its chlorine, acid, and alkali resistance.
- Seats: Durable PTFE (Teflon®) or EPDM/FKM for superior chemical sealing.
- Union Ends: Available in socket, threaded (NPT/BSPT), or flanged, catering to diverse installation standards.
- Actuation Options: Manual/lever handle (~95% of installations) or pneumatic/electric actuator for automated processes.
