All-plastic stop valve

Supplier of specialty polymers, Solvay’s high-performing Radel polyphenylsulfone (PPSU) polymer has enabled China-based CiXi Zhenpeng Plumbing Fittings Company to replace traditional brass in a new line of all-plastic valves targeting pressurised hot water systems used in HVAC applications.

Among Zhenpeng’s new products is what is said to be the industry’s first all-PPSU stop valve to meet standards ASME A112.18.1-2012 and CSA B125.1-12, as tested by the International Association of Plumbing and Mechanical Officials (IAPMO).

“Because stringent global regulations discourage the use of brass in pipe fittings for drinking water and HVAC systems, leading-edge innovators like CiXi Zhenpeng have increasingly sought to leverage Solvay’s 30 years of experience in specialty polymer technology for this market,” said Philippe-Jacques Leng, global construction market manager for Solvay’s Specialty Polymers Global Business Unit. “Zhenpeng’s innovative all-PPSU stop valve did not simply reduce the presence of heavy metals in the part, it eliminated them entirely to offer system integrators a safer and more durable alternative for their customers.”
