DESCRIPTION APPLICATION
Direct operated 2-way pressure reducing valve in screw-in cart- Pressure reducing valves are used to maintain the pressure in a
ridge construction for cavity according to ISO 7789. Oil flows from consumer constant independent of pressure fluctuations on the
P (2) to A (1) (and vice versa) as long as the pressure in A (1) is lower supply side. In the case of several consumers, the pressure of the
than the value set on the adjusting screw. Otherwise the valve is specific consumers can be individually adjusted by the pressure
closed seat-tight, even if the pressure drops in P (2). If the pressure reducing valve. The screw-in cartridge is perfectly suitable for
in P (2) is sufficiently high, the valve ensures that the pressure in A installation in control blocks. For machining the cartridge cavity in
(1) is regulated to the set value. Turning in the adjusting screw steel and aluminum blocks, cavity tools are available (hire or

Note! An inadmissibly high pressure in port A (1) when the
valve is closed, has eventually to be avoided by a
separate pressure relief valve.
