The Bosch Rexroth ZDR10DP2-5X/75YM (R900410875) is a meticulously engineered industrial hydraulic valve designed for direct operation and reliable pressure reduction in various hydraulic systems. This valve, part of the high-performance range, features a spool valve that is directly operated and allows for mechanical actuation. It comes with an adjustment range up to 75 bar and can maintain a consistent pressure level thanks to its robust design.
The ZDR10DP2-5X/75YM valve is characterized by its size 10 interface, conforming to both NFPA T3.5.1 R2 D03 and ISO 4401 standards, which ensures compatibility with a wide range of sandwich plate connections. The maximum operating pressure this valve can withstand is 315 bar, while it can facilitate a maximum flow of 80 liters per minute, making it suitable for various hydraulic applications requiring precise pressure control.
Equipped with NBR seals, the ZDR10DP2-5X/75YM is compatible with multiple types of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC. Its versatility extends to the number of ports available and includes an option for mechanical actuation. Additionally, this model offers different versions (A, P, B) to cater to specific circuit configurations and requirements.
The unit's design incorporates a control spool sided by a compression spring that allows users to set secondary pressures accurately through an adjustment type mechanism. The inclusion of an optional check valve facilitates free flow back from channel A in version A of the valve. For monitoring purposes, there is also provision for a pressure gauge connection.
In summary, the Bosch Rexroth ZDR10DP2-5X/75YM (R900410875) stands out as a high-quality pressure reducing valve suitable for applications where precise control over system pressure is essential. Its robust construction and adaptability make it an ideal choice for demanding hydraulic tasks.

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!
