Our range includes pressure relief valves in different mounting styles and for a variety of application areas: industrial as well as mobile, for the use in hydraulic and pneumatic systems, for fluid and gas handling, process control and refrigeration.

Brass or steel Pressure Relief Valve for medium pressure applications up to 250 bar.

The Parker VR7 Series Pressure Relief Valve is designed to ensure safety and protection of downstream process equipment by venting excess pressure from a regulator should a minor seat leak occur. It is available in stainless steel.

The RAH161 Series, Pilot Operated, Spool-Type Relief Valves are suited for continuous duty applications and are primarily used to limit main system pressure. When inlet pressure exceeds the valve setting, the pilot section opens.

Introduction: High Pressure Relief Valve The Parker High Pressure Relief Valve (HPRV) provides an automatic protection mechanism for process instrumentation systems. When upstream pressure exceeds the closing force exerted by the valve’s spring, the lower stem opens and permits flow through the valve’s outlet port - which can

Series RVP relief valves provide reliable venting of gases or liquids for set pressures from 3,000 psi (205 bar) minimum to 75,000 psi (5170 bar). The standard temperature range for all models is -423° to 400°F (-252° to 204°C).

Parker pilot operated pressure relief valves for in-line mounting series R4V provide an outstanding constant pressure behaviour. Series R4V*P2 enables a continuous pressure adjustment by the additional proportional unit.

These pressure relief valves protect hydraulic system components by limiting pressure by directing excess pressure to the tank. Adjustable relief valves open in one direction at an adjustable pressure rating to protect downstream components, featuring a knob to set desired opening pressure. Loading...

Parker pressure relief valves are designed such that when upstream pressure exceeds the closing force exerted by the spring, the lower stem opens, permitting flow through the valve.

Parker’s pilot operated pressure relief valves series R and RS*E in slip-in cartridge design are particularly suitable for the protection of the pump and feature an excellent pressure behaviour for improved process accuracy.
