The PVC ball valve combines the chemical resistance of the polymer with a leak-proof, tight seal: by rotating the ball 90°, it completely seals the fluid flow without any detectable leakage, regardless of the flow direction. Unlike a PVC butterfly valve—whose disc may develop micro-leaks over time with frequent closing—the PVC ball seals by perfect compression of the sphere against two PTFE seats, maintaining that seal throughout the valve's lifespan. At Cematic, we supply PVC ball valves for temperatures up to 60 °C, and soon CPVC for hot water applications up to 93 °C, available with threaded connections and True Union fittings for quick, tool-free disassembly.
