RVP Series Relief Valve

Metal Seat Relief Valves


Parker Autoclave Engineers relief valves provide reliable venting of gases or liquids for set pressures from 1,500 psi (103 bar) to 75,000 psi (5171 bar). These precision valves are designed for pressure gas systems, cryogenic systems, petrochemical applications and other special systems.


  • Relief valves designed to open as a function of increasing system pressure.

  • Orifice sizes are based on valve pressure ranges.

  • High set pressure capability.

  • Constructed of 316 SS with selected components made of anti-galling stainless material.

  • Temperature range from -423°F (-252°C) to 400°F (204°C).

  • High temperature option to 750°F (399°C)

  • Fewer parts, ease of maintenance.

  • CE mark option.

Parker Autoclave RVP relief valves provide system over pressure protection primarily for thermal expansion of low volume relief applications at high pressure where flow is not critical. The metal seat relief valves are capable of handling air, gases, steam, vapor, and liquids however are not recommended for steam boiler applications and cannot be ASME code stamped.
