With abundant experience, we warmly welcome you to buy high quality ppr double union ball valves for sale here from our factory. Also, pricelist and free sample are available.
The PPR double union ball valves is a core on-off control valve for PPR piping systems. Its valve body is injection-molded from random copolymer polypropylene, while a spherical valve core enables rapid full open and full close. The double union nuts at both ends allow replacement without cutting the pipe, combining the sealing performance of fusion joints with the convenience of a union design. Widely used in cold and hot water supply systems, it is an essential fitting for PPR piping.
Product Advantages
Double Union - No Pipe Cutting
Loosen the two union nuts to remove the valve body without cutting the pipe or damaging existing fusion joints, reducing maintenance costs.
Spherical Valve Core - Self-Sealing
A high-precision core seats tightly for smooth 90° operation; higher pressure produces a tighter seal, preventing leakage over the long term.
Food-Grade Material
Made from PPR raw material approved for drinking water contact - non-toxic with no substance migration. Paired with high-temperature silicone seals, it is suitable for direct drinking water.
Broad Compatibility
Standard PPR fusion sockets fuse directly with same-size pipes and fittings. Lightweight and tool-free installation.
