The Bosch Rexroth DR6DP1-5X/150YM/12 (R900554887) is a high-performance industrial hydraulic valve designed for reliable pressure reduction from the supply pressure to a predetermined setting value. This direct-actuated spool valve comes equipped with a mechanically actuated P to A spool and features an adjustable spindle with an external hexagon and protective cap, allowing for precise pressure adjustments within its range. The model also includes an adjustable screw with external hexagon and protective cap, ensuring secure settings during operation. The DR6DP1-5X/150YM/12 is engineered for subplate mounting and adheres to porting patterns according to DIN 24340 form A and ISO 4401 with an optional locating hole. It boasts various adjustment types including a rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, or a rotary knob with scale. Additionally, the inclusion of a check valve is optional based on specific application requirements. With a maximum operating pressure of up to 315 bar and capable of handling maximum flow rates as specified by the manufacturer, this valve is designed for robust use in various hydraulic systems. The product also features pilot oil return via an external channel, measuring ports with SAE thread for monitoring purposes, and NBR seals compatible with hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. This particular model is part of Productgroup ID series X and comes in size 6. Its weight is meticulously calibrated to ensure optimal performance without adding unnecessary bulk to the system it serves. The DR6DP1-5X/150YM/12 valve's primary function is to maintain constant pressure levels in secondary circuits while allowing for free flow back from channel A to channel P when paired with an optional check valve. This capability ensures that hydraulic systems operate efficiently and effectively under varying loads and conditions.
Size 6, P → A, mechanically actuated
Industrial hydraulic valve in a high performance range. Reliable pressure reduction of the supply pressure to setting value.

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.
