Coliter ® PPR Male Thread Ball Valve – PN20, Lead-Free Brass Core
QF2009 PPR Male Thread Ball Valve – Lead-Free Brass Core with PP-R Body for Hot & Cold Water Systems
The Coliter® QF2009 PPR Male Thread Ball Valve is a specialized hybrid valve designed for polypropylene (PP-R) piping systems in residential and commercial hot and cold potable water applications. It features a **pure PP-R body** on one end for direct heat-fusion welding to PP-R pipes, and a **male BSP thread (ISO 228)** on the other end for connection to metal fittings or equipment. The internal shut-off mechanism uses a **lead-free brass ball core** with PTFE seals, ensuring reliable bubble-tight closure, full-port flow, and smooth quarter-turn operation. Rated at **PN20 (2.0 MPa) at 20°C** and suitable for continuous service up to **95°C**, it complies with **ISO 15874 and GB/T 15564** standards. Ideal for solar water heaters, underfloor heating manifolds, and appliance connections where corrosion-free, long-life performance is required.
