Coliter ® PPR Union Ball Valve – PN20, Lead-Free Brass Core
QF2010 PPR Union Ball Valve – Lead-Free Brass Core with PP-R Body for Hot & Cold Water Systems
The Coliter® QF2010 PPR Union Ball Valve is a hybrid valve designed specifically for polypropylene (PP-R) piping systems in residential and commercial hot and cold potable water applications. It features a **pure PP-R body** fused directly to the pipeline via heat welding, eliminating metal-to-plastic joints and preventing corrosion or scaling. The internal shut-off mechanism consists of a **lead-free brass ball core** with PTFE seals, ensuring reliable bubble-tight closure and smooth quarter-turn operation. Rated at **PN20 (2.0 MPa) at 20°C** and suitable for continuous use up to **95°C**, it complies with **ISO 15874 and GB/T 15564** standards. The double union design allows easy installation and future maintenance without pipe cutting. Ideal for underfloor heating, solar water systems, and drinking water networks where long-term chemical resistance and leak-free performance are essential.
