PPR Ball Valve: Technical Specifications and Features

نظرة عامة على المنتج

PPR ball valves are high-performance flow control devices designed specifically for polypropylene piping systems. These valves combine the durability of PPR material with the reliable operation of a ball valve mechanism, creating an ideal solution for both residential and industrial applications. The unique design integrates a brass or stainless steel ball with PPR body components, offering superior corrosion resistance while maintaining excellent sealing performance.

تكوين المواد

The valve body is constructed from high-quality polypropylene random copolymer (PPR), ensuring chemical resistance and long-term durability. The ball component typically consists of chrome-plated brass or stainless steel for smooth operation and reliable sealing. Stem seals are made from PTFE or EPDM, providing excellent wear resistance and leak-proof performance. All materials comply with drinking water standards (NSF/ANSI 61) and are lead-free.
