Pressure relief valve with pilot control

         

The valve is closed in the idle position. The hydraulic fluid drains off at T, when the pressure difference at the connections P and T exceeds the nominal pressure. If the pressure falls below the preset value, the valve closes again. The flow direction is marked with an arrow.

The pilot operated pressure relief valve consists of a pilot stage and a main stage. When open, there is less volumetric flow at the pilot stage that leads to connection Y.

The hydraulic resistance relates to the completely opened valve.

Adjustable parameters

          Nominal pressure:         0 ... 40 MPa         (5)

     Hydraulic resistance:         1e-7 ... 100 MPa*min2/l2 (0.01)
