Coliter ® PPR Male Thread Union Ball Valve – PN20, Lead-Free Brass Core
QF2003 PPR Male Thread Union Ball Valve – Lead-Free Brass Core with PP-R Body
The Coliter® QF2003 PPR Male Thread Union Ball Valve is a 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 BSP male thread with an integrated union nut on the other end—enabling secure connection to female-threaded fittings while allowing easy disassembly for maintenance without cutting the pipeline. The internal shut-off mechanism uses a lead-free brass ball core with PTFE seals, ensuring full-port flow, bubble-tight sealing, 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, water heaters, and appliance connections where long-term corrosion resistance and serviceability are essential.
