pilot operated pressure relief valve

A pilot-operated valve consists of a body, top plate, and pilot control. The main valve responds to what the pilot control tells it. 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.

Pilot-operated valves are pressure relief valves that control the main valve's inlet and outlet port. They are similar to spring-loaded valves but are the best alternative solution for reaching the highest pressure and highest capacity. These valves offer excellent performance for overpressure protection.

Size 6 · Component series 1X · Max. operating pressure 315 bar · Flow, max. 40 l/min.

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.

The pilot operated pressure relief valve is a self-contained system which does not require any external power or pressure source. The pilot valve, using 

The Duplomatic PRE* valves are pilot operated pressure relief proportional valves with mounting interface in compliance with ISO 6264 standards (CETOP RP 121H). These valves are normally used to control hydraulic circuit pressure and enable the use of the full flow rate of the pump, even with settings approaching calibrated values.

There are several configurations available for both conventional and pilot operated pressure relief valves, so each application should be considered carefully when selecting and specifying a pressure relief valve. AWC's team of trusted resources is here to assist with application review, selection, sizing, training, maintenance, and asset

HTXD series pilot operated pressure relief valve has two basic types, ie，the pop action type and the modulating action type. For the pop action, the main valve will snap open fully with Ittle over pressure; for the modulating action, the lit of main valve is in proportion
