PROGEF Standard PP-H check valves prevent backflow in industrial socket fusion piping networks. The range includes Type 561 and Type 562 true double union non-return valves, as well as Type 369 wafer check valves, designed for reliable operation in aggressive fluid handling. Manufactured from high-grade beta PP-H, these valves provide exceptional chemical resistance and thermal stability up to PN10 operating pressures. They are widely specified in chemical processing, industrial effluent treatment, and water treatment systems.
