Pilot operated pressure relief valve able to operate at considerably higher set pressure than with spring loaded safety relief valves, the valve operation and lift are unaffected by back-pressure. Valve silencers Noise in some safety and control valves generates levels above 150 dBA / dBC, a situation that is a concern for the technical operations and maintenance of plants.
Learn MoreLike other pressure relief valves (PRV), Pilot operated relief valves ( PORV) are used for emergency relief during overpressure events (e.g., a tank gets too hot and the expanding fluid increases the pressure to dangerous levels). The difference between PORV and conventional PRV is that pilot valves use system pressure to seal the valve.

The introduction of system pressure to the inlet of the valve. The sense line sensing the pressure and rerouting some of it to the pilot control through this tubing.
Learn MorePilot operated pressure relief valves series R4V (TÜV) (DIN 24340 Form D) and R6V (TÜV) (DIN 24340 Form E) include a certification according to directive /68/EU for the usage for safety-related applications. The valve is set and sealed by the German technical inspection association TÜV.
Learn MorePilot Operated Pressure Relief Valve, SAE Flange - Series R5V / R5V*P2. Parker pilot operated pressure relief valves series R5V and R5V*P2 provide an outstanding constant pressure behaviour. The SAE flanges allow to mount the valves directly on the flanges of pumps or actuators to achieve a very compact design.

Learn More2022/7/14 · Pilot valves are high-flow control valves for a system. The pressurized fluids mostly move the pilot-operated valves. When the set pressure is achieved, the valve opens and the pressure is released. The flow directing element of the valve changes when pressured fluid meets the valve piston.

Learn MoreOur pilot operated pressure reducing valves are designed specifically for Fire Suppression Systems to reduce high inlet pressures to a safe and stable outlet pressure. The pilot assembly reacts to changes in downstream pressure allowing the main valve to modulate between the closed and open position insuring a constant downstream set pressure. Once the downstream
