The Bosch Rexroth Z3DR6VP2-1X/50MSV/12 (R901161012) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a preset value. This spool valve is pilot-operated, with a pressure adjustment range that ensures precise control of secondary pressures. It features a sleeve with a hexagon and protective cap, and it belongs to component series X, indicating its compliance with the latest engineering standards. The Z3DR6VP2-1X/50MSV/12 valve has a maximum pressure capacity and is suitable for various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. It comes equipped with FKM seals which are known for their chemical resistance and durability. The valve is designed with multiple ports and allows mechanical actuation. This model's capabilities include flat discharge pressure curves for consistent performance, high stability across operations, and minimal hysteresis. A unique feature of this version MS is the ability to measure and monitor the set secondary pressure through a measuring port which facilitates the maintenance and adjustment processes. In case of an overpressure scenario at the actuator port P, the Z3DR6VP2-1X/50MSV/12 will open an additional line to the tank port T to safeguard against any undue pressure increase. This safety feature ensures protection for both the system and components involved. The sandwich plate design of this valve allows for easy integration into various systems with connection diagrams conforming to NFPA T3.5.1 R2 D03 Size 6 CETOP D03 standards as well as ISO 4401 size 03 patterns. With its robust build quality and versatile application potential in controlling secondary pressures in hydraulic systems, this Bosch Rexroth valve represents precision engineering tailored for demanding industrial environments.

Industrial hydraulic valve in a high performance range. Reliable pressure reduction to setting value.
Unpacked Weight: 1.290 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.
