DESCRIPTION APPLICATION
Pilot operated pressure reducing valve in screw-in cartridge cons- The integrated pressure relief makes an additional pressure relief
truction for cavity according to ISO 7789. The valve reduces the valve in the consumer line superfluous. In the case of several
input pressure to an adjustable output pressure. Through the integ- consumers, the pressure of the specific consumers can be individu-
rated pressure relief function, exceeding the reduced pressure as a ally adjusted by the pressure reducing valve. Pressure reducing
result of external forces is avoided. The pressure reducing valve valves are used to maintain the pressure in a consumer constant
controls the pressure in port A (1). Through increasing the spring independent of pressure fluctuations on the supply side. The
tension, the pressure in port A(1) rises. The valve operates practi- screw-in cartridge is perfectly suitable for installation in control
cally independently of the pressure in port P (2). Pressure increase blocks. For machining the cartridge cavity in steel and aluminum
in port A (1) to above the adjusted value, e.g. through an active blocks, cavity tools are available (hire or purchase). Please refer to
