Parker pilot operated pressure relief valves series SCRM ensure a long service life due to valve bodies manufactured from steel. The sandwich design enables an easy configuration of stack systems. Depending on type, pressure limiting can be achieved in ports P, A or B with unloading to port T. SCRM valves may only be mounted in the defined

Like 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.

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 to the overpressure to make sure that the curtain area changes with the discharge. the two types is the basic pilot

The pressure relief valve can be unloaded or switched to another pressure (second pressure rating) via port X (15). General Pressure valves of type DB and DBW are pilot-operated pressure relief valves. They are used for limiting (DB) or limiting and magnetically unloading (DBW) the operating pressure.

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.
