The Bosch Rexroth ZDR6DP2-4X/210YMV/12 (R900500035) is a mechanically actuated industrial hydraulic valve designed for reliable pressure reduction to a preset value within hydraulic systems. This direct-operated spool valve is part of Bosch Rexroth's high-performance range and is notable for its robust construction and precise pressure control capabilities. It features a size 6 CETOP D interface, conforming to ISO and NFPA T3.5.1 R2 D03 standards, allowing for versatile integration into various hydraulic circuits.
The valve is equipped with a sleeve with hexagon and protective cap for adjustment, ensuring secure settings and preventing inadvertent changes in pressure levels. The pressure adjustment range spans up to 210 bar, supporting a max flow rate of up to 80 liters per minute, which makes it suitable for applications requiring substantial fluid throughput without compromising on control or efficiency.
With multiple ports and switching positions available, the ZDR6DP2-4X/210YMV/12 provides flexibility in system design and application. The valve's actuation is mechanical, which ensures consistent performance even in demanding operational conditions. The weight of the valve is optimized to maintain balance within the system while still offering robustness needed for industrial applications.
The ZDR6DP2-4X/210YMV/12 utilizes FKM seals compatible with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR types. This compatibility range ensures that the valve can be employed in diverse environments with different fluid requirements without compromising seal integrity or performance.
Additionally, it incorporates an external leakage oil drain via bore from the spring chamber to ensure system cleanliness and efficiency. A pressure gauge connection facilitates monitoring of secondary pressure directly at the valve for maintenance or system checks. Optional check valves are available in version A only for free flow back from channel A to A.
In summary, the Bosch Rexroth ZDR6DP2-4X/210YMV/12 offers precise pressure reduction in high-performance hydraulic systems with its direct operation design and versatile configuration options catering to rigorous industrial demands.

• Rotary knob with scale Pressure reduction in channel A, B or channel P Check valve, optional (version “A” only) Corrosion-protected design
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.
