The Bosch Rexroth Z3DR6VP2-1X/50V (R901160091) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a preset value. This spool valve is pilot-operated and features pressure adjustment capabilities within a defined range. It is equipped with a sleeve that has a hexagon shape and protective cap, ensuring durability and safety during operation. The Z3DR6VP2-1X/50V valve boasts a component series X designation, indicating its adherence to rigorous quality and performance standards. The spool symbol P P denotes the specific configuration of the valve's ports and its maximum pressure capability. With multiple ports available, this valve offers versatility in connection options, including a sandwich plate design that adheres to NFPA T3.5.1 R2 D03 Size 6 and CETOP D03 standards, as well as ISO 4401 porting patterns. The maximum flow rate for this model is well-suited for various applications requiring precise control of fluid dynamics within hydraulic systems. The valve includes several switching positions and weighs in at an efficient . kg, making it suitable for integration into numerous setups without adding excessive weight. This model utilizes FKM seals compatible with an extensive range of hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. These features ensure that the Z3DR6VP2-1X/50V can handle diverse operating conditions while maintaining its integrity and performance levels. Moreover, the Bosch Rexroth Z3DR6VP2-1X/50V valve is characterized by its flat discharge pressure curves for stable operation and minimal hysteresis effects. The optional MS version supports the measurement of secondary pressure via an integrated load cell at the measuring port. Additionally, if there's an excessive rise in secondary pressure at the actuator port P beyond the set value, the valve diverts excess flow to tank port T to protect against undue pressure increases. This model offers various adjustment types for precise control: either through a spindle with internal hexagon or via a lockable rotary knob with scale for easy monitoring of settings. Its corrosion-protected design ensures longevity even in harsh environments. With size 6 dimensions and rated for maximum operating pressures up to bar with flows reaching l/min., this sandwich plate valve is engineered to meet stringent operational requirements while delivering consistent performance.


Size 6, P2 → P1, mechanical

Industrial hydraulic valve in a high performance range. Reliable pressure reduction to setting value.

Unpacked Weight: 1.270 kg

Valve type Z3DR are pilot-operated 3-way pressure reducing valves in sandwich plate design with pressure limitation of the actuator. They serve for reduction and control of secondary pressure.

The valves basically consist of pilot control valve (1) and housing (2) including main stage. The secondary pressure is set via the adjustment type (3).

Rexroth pilot-operated pressure reducing valves feature flat discharge pressure curves, high stability and low hysteresis.

Version "MS" enables measurement and monitoring of the set secondary pressure via a pressure load cell at the measuring port (4) (refer to Dimensions).

If the secondary pressure at actuator port P① further exceeds the set value, the third line to tank port T is opened by the valve. This way, the actuator channel is protected against inadmissible pressure rise.
