ساختار ردیوسینگ رکسروت ZDR6

The valve type ZDR is a direct operated pressure reducing valve in sandwich plate design with pressure limitation of the secondary circuit.

It is used to reduce the system pressure.
The pressure reducing valve basically comprises housing (1), control spool (2), compression spring (3), adjustment type (4) and an optional check valve.

The secondary pressure is set via the adjustment type (4). Version “A” The valve is open in initial position. Hydraulic fluid can flow from channel A① to channel A② without restrictions.

The pressure in channel A② is simultaneously applied via the control line (5) at the piston area opposite the compression spring (3). If the pressure in channel A② exceeds the value set at the compression spring (3), the control spool (2) is pushed against the compression spring (3) to control position and keeps the set pressure in channel A② at a constant level. Control signal and pilot oil are supplied internally via the control line (5) from channel A②.

If the pressure in channel A② increases further due to an external force effect at the actuator, it pushes the control spool (2) even further against the compression spring (3).

In this way, channel A② is connected to the tank via the control edge (9) at the control spool (2) and the housing (1). So much hydraulic fluid is discharged into the tank that the pressure does not increase any further. The leakage oil drain from the spring chamber (7) is always effected externally via the bore (6) and channel T (Y). A pressure gauge connection (8) allows for the control of the secondary pressure at the valve. A check valve can be used for free flow back from channel A② to A① with version “A”. Versions “P” and “B” With version “P”, the pressure reduction is effected in channel P①. Control signal and pilot oil are supplied internally from channel P①. With version “B”, the pressure is reduced in channel P①; but the pilot oil is extracted from channel B.
