Functional description of 4 adjustment elements pilot operated pressure relief valve:
Pressure relief valve types ZDB and 22DB are pilot operated and are of sandwich plate design. They are used to limit the pressure within a hydraulic system. They basically consist of the housing (7), together with one or two pressure relief valve cartridges.
The system pressure is set by means of adjustment element (4).
At rest, the valve is closed. Pressure in port A acts on the spool (1). At the same time pressure passes through orifice (2) on to the spring loaded side of spool (1) and via orifice (3) to the pilot poppet (6). If the pressure in port A rises above the value set on spring (5), the pilot poppet (6) opens. Fluid can now flow from the spring loaded side of spool (1), orifice (3), and channel (8) into port T. The resulting pressure drop then moves spool (1), causing this to open connection A to T, while the pressure set at spring (5) is maintained.
Pilot oil from the two spring chambers returns externally to tank via port T.
