The Bosch Rexroth DR6DP2-5X/150YM/12 (R900479792) is a high-performance industrial hydraulic valve designed for reliable pressure reduction from the supply pressure to a set value. This spool valve is directly actuated and features a pressure adjustment range up to 315 bar. It includes an adjustable spindle and screw, both with external hexagons and protective caps, ensuring easy and secure adjustments. The valve also has a pilot oil return, external measuring port with an SAE thread, and uses NBR seals compatible with hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC.
The DR6DP2-5X/150YM/12 is designed for subplate mounting with connection diagrams that conform to NFPA T3.5.1 R2 D03 and ISO 4401 standards. It has multiple ports for versatile applications and can support a maximum flow rate as specified by the manufacturer. The valve's mechanical actuation allows for precise control in various hydraulic systems.
This model features an initial open position that permits unrestricted flow from channel P to A until the desired secondary pressure is reached. Once the set pressure is exceeded due to external forces on the actuator, the control spool adjusts accordingly to maintain a constant pressure level by discharging excess hydraulic fluid into the tank through channel TY.
An optional check valve can be installed for free flow back from channel A to P, enhancing functionality. A pressure gauge connection is included for monitoring secondary pressure levels effectively. With its robust design and precise control capabilities, the Bosch Rexroth DR6DP2-5X/150YM/12 serves as an essential component in complex hydraulic systems requiring dependable pressure regulation.

The valve type DR 6 DP is a direct operated pressure reducing valve in 3-way version, i. e. with pressure limitation of the secondary circuit.
It is used to limit a system pressure. The secondary pressure is set via the adjustment type (4)
The valve is open in initial position. Hydraulic fluid can flow from channel P to channel A without restrictions. The pressure in channel A is simultaneously applied via the control line (6) at the piston area opposite the compression spring (3). If the pressure in channel A exceeds the value set at the compression spring (3), the control spool (2) moves to control position and keeps the set pressure in channel A at a constant level.
Signal and pilot oil come internally via the control line (6) from channel A.
If the pressure in channel A 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 A is connected to channel T(Y) via the control edge (8) at the control spool (2). So much hydraulic fluid is discharged into the tank that the pressure can only increase slightly.
The leakage oil discharge from the spring chamber (7) is always effected externally via channel T(Y).
For the free flow back from channel A to channel P, a check valve (5) can optionally be installed.
A pressure gauge connection (1) allows for the control of the secondary pressure.
