DESCRIPTION APPLICATION
Pilot operated pressure reducing valve in screw-in cartridge const- The integrated pressure relief makes an additional pressure relief
ruction for cavity according to ISO 7789. The valve reduces the input valve in the consumer line superfluous. In the case of several consu-
pressure to an adjustable output pressure. Through the integrated mers, the pressure of the specific consumers can be individually ad-
pressure relief function, exceeding the reduced pressure as a result justed by the pressure reducing valve. Pressure reducing valves are
of external forces is avoided. The pressure reducing valve controls used to maintain the pressure in a consumer constant independent
the pressure in port A (1). Through increasing the spring tension, the of pressure fluctuations on the supply side. The screw-in cartridge is
pressure in port A(1) rises. The valve operates practically indepen- perfectly suitable for installation in control blocks. For machining the
dently of the pressure in port P (2). Pressure increase in port A (1) to cartridge cavity in steel and aluminum blocks, cavity tools are availa-
above the adjusted value, e.g. through an active consumer, is avoided ble (hire or purchase). Please refer to the data sheets in register 2.13.
by discharging excess oil to the tank (3). The stainless execution is
especially suitable for the use in wet and salty environment.
