PRP Pressure Relief Valve - Large Diameter
The high-capacity PRP is the most powerful thermoplastic pressure relief valve available for large nominal diameters from 2½” - 4”. The PRP is the only pressure relief valve in the world that also functions as a check valve for the most reliable upstream pressure maintenance available anywhere.
Available sizes: 2½”, 3", 4” (75mm - 110mm)
Body Materials: PVC, PP, PVDF
Seals: EPDM, Viton
Connections: Spigot or Flange
This PRP is designed for larger nominal diameters (up to 4”), with each size available it a choice of two pressure ranges and connection types. The PRP is equipped with a patented piston controlled mechanism so it is completely free of return pressure and acts as a non-return (check) valve simultaneously. These valves can be precisely adjusted even under full operating pressure. The high quality PTFE coating on the control diaphragm makes the valve suitable for a wide range of aggressive medium types. Due to the special piston design, the PRP maintains a constant operating pressure even in case of back pressure caused by many closed-loop systems.
