The Bosch Rexroth ZDR10DP2-5X/150YM/12 SO30 (R978865925) is a high-performance direct operated pressure reducing valve designed for efficient control of system pressure in hydraulic circuits. This sandwich plate valve is engineered to provide precise pressure limitation in a secondary circuit by reducing the system pressure according to the set parameters. It features a robust housing, a responsive control spool, and a durable compression spring for reliable operation.
The valve's secondary pressure is adjustable, allowing users to set the desired level of pressure via an adjustment mechanism. In its initial position, the ZDR10DP2-5X/150YM/12 SO30 allows free flow from channel A to channel A without restriction, maintaining constant pressure through the balance of forces on the control spool and compression spring. The design includes an optional check valve for free flow return in version A.
For different applications, versions P and B cater to varying requirements; version P controls pressure reduction in channel P with internal pilot oil supply from channel P, while version B reduces pressure in channel P but sources pilot oil from channel B.
This model incorporates external leakage oil drain from the spring chamber via channel TA and provides a pressure gauge connection for monitoring secondary pressure directly at the valve. Depending on the application needs, it can be used with or without a directional valve.
The ZDR10DP2-5X/150YM/12 SO30 adheres to ISO standard porting patterns and offers various adjustment types including rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale. With its size component series X, this valve supports maximum operating pressures up to bar and maximum flow rates measured in liters per minute. This makes it suitable for diverse hydraulic applications where precise control of reduced system pressures is essential.

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 A➀ to channel A➀ without restrictions. The pressure in channel A➀ is simultaneously applied via the control line (5) at the piston area opposite the compression spring (3). If the pressure in channel A➀ 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 A➀ at a constant level.
Control signal and pilot oil are supplied internally via the control line (5) from channel A➀.
If the pressure in channel A➀ 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 A➀ is connected to the tank (channel TB) via the control edge (6) 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 channel TA.
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 A➀ to A➀ with version “A”.
Versions “P” and “B”
For version “P”, the pressure reduction is effected in channel P➀. Control signal and pilot oil are supplied internally from channel P➀.
For version “B”, the pressure is reduced in channel P➀; but the pilot oil is extracted from channel B. If the directional valve is in spool position P to A, the pressure in channel B may not exceed the set secondary pressure. Otherwise, there is pressure reduction in channel A.
Attention!
If used without directional valve, channels TA and TB are connected to each other (e. g. in the cover plate). During set-up of a directional seat valve NG 10, a sandwich plate type HSZ10A078-3X/M00 (material no. R900537264) has to be used.Type ZDR 10 DA …

Notices!
Length and tightening torque of the valve mounting screw must be calculated in connection with the components mounted underneath and above the sandwich plate valve. To port X and Y bored according to ISO 4401-05-05-0-05 (e. g. for pilot-operated directional valve NG 10), version “SO30” applies at the end of the ordering code!
