DESCRIPTION APPLICATION
Direct operated pressure reducing valve in screw-in cartridge The integrated pressure relief makes an additional pressure relief
construction for cavity according to Wandfluh standard. The valve in the consumer line superfluous. In the case of several
valve reduces the input pressure to an adjustable output pres- consumers, the pressure of the specific consumers can be indivi-
sure. Through the integrated pressure relief function, exceeding dually adjusted by the pressure reducing valve. Pressure reducing
the reduced pressure as a result of external forces is avoided. valves are used to maintain the pressure in a consumer constant
The pressure reducing valve controls the pressure in port A (1). independent of pressure fluctuations on the supply side. The
Through increasing the spring tension, the pressure in port A(1) screw-in cartridge is perfectly suitable for installation in control
rises. The valve operates practically independently of the pres- blocks. For machining the cartridge cavity in steel and aluminum
sure in port P (2). Pressure increase in port A (1) to above the blocks, cavity tools are available (hire or purchase). Please refer to
