Coliter®’s PPR radiator valves (including NQ2008-H, NQ2008-C, NQ2009-H) are specially designed for modern plastic-based heating systems using PP-R (polypropylene-random) piping. These valves combine a pure PP-R body with a brass ball core and stem, enabling reliable shut-off and flow control while maintaining full compatibility with heat-fusion PP-R pipe networks. Available in angle and straight configurations, they feature standard G1/2" female threads for radiator connections and are rated for PN20 (2.0 MPa) at 20°C and continuous operation up to 70–95°C. Ideal for underfloor heating manifolds, radiator branches, and energy-efficient homes—eliminating metal-to-plastic transition joints, reducing leak points, and ensuring long-term corrosion resistance.
