The Bosch Rexroth ZDR6DB2-4X/210YM (R900463269) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a preset value. This spool valve is direct operated and features mechanical actuation, allowing for precise control in various hydraulic applications. It comes equipped with a sleeve with hexagon and protective cap, ensuring durability and ease of maintenance.
With its capability to adjust pressure within a range of up to 210 bar, the ZDR6DB2-4X/210YM valve ensures consistent performance under demanding conditions. It offers a maximum flow rate, making it suitable for systems requiring substantial fluid throughput. The valve is designed for sandwich plate mounting and conforms to the NFPA T3.5.1 R2-2002 D05 and ISO 4401 porting patterns, providing versatility and ease of integration into existing hydraulic systems.
The model features multiple ports for flexible connection options and can be configured with various actuation types according to specific application needs. The available spool symbols include P over P, indicating the flow path of the hydraulic fluid through the valve.
Constructed with NBR seals, this valve is compatible with a range of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC types. The robust design ensures that it can withstand harsh operating conditions while maintaining efficient operation.
Additional features include an optional check valve in version A for free flow back from channel A to A, external leakage oil drain from the spring chamber via bore T Y, and a pressure gauge connection for monitoring secondary pressure directly at the valve.
In summary, the Bosch Rexroth ZDR6DB2-4X/210YM (R900463269) offers precise pressure reduction capabilities in a compact form factor that is suitable for various industrial applications requiring dependable hydraulic control.

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.
