The Bosch Rexroth ZDR6DP2-4X/210YMV (R900400663) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a predetermined setting value. This direct-operated spool valve is part of the sandwich plate design, which allows for easy integration into hydraulic systems. It features a pressure adjustment range that ensures versatility for various applications and comes equipped with a sleeve with hexagon and protective cap for adjustment.
With its spool symbol P P, the ZDR6DP2-4X/210YMV can handle a maximum pressure of 210 bars, making it suitable for demanding environments. It has multiple ports and mechanical actuation, providing precise control over hydraulic flow. The maximum flow capacity of this model is substantial, ensuring efficient system performance.
For connection purposes, this valve adheres to the NFPA T3.5.1 R2 D03 and ISO 4401 porting patterns and can be easily mounted using the sandwich plate design. The valve's weight and FKM seals ensure durability and compatibility with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR.
The ZDR6DP2-4X/210YMV valve is designed to maintain constant pressure levels in hydraulic systems by releasing excess fluid into the tank when necessary. It also features external leakage oil drainage from the spring chamber and provides a pressure gauge connection for monitoring secondary pressure directly at the valve.
This model offers different versions: A allows free flow back from channel A to A with an optional check valve; P focuses on reducing pressure in channel P; B reduces pressure in channel P while extracting pilot oil from channel B. Each version is tailored to specific circuit requirements ensuring optimal performance in various configurations.
In summary, the Bosch Rexroth ZDR6DP2-4X/210YMV offers robust construction, precise control capabilities for secondary circuit pressure reduction, multiple versions for application-specific needs, and compatibility with numerous hydraulic fluids – all within a compact sandwich plate design that simplifies installation and maintenance.

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 A➁.
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 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 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.
Notice:
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.
