The Bosch Rexroth DR6DP2-5X/150YV (R900474897) is a direct operated pressure reducing valve designed for subplate mounting with a way version to limit system pressure. This model ensures the secondary circuit's pressure is controlled and maintained at a constant level, as set by the user through the adjustment type. The valve's initial open position allows free flow from channel P to A, with the pressure in channel A being regulated by the piston area opposite to the compression spring.
When external forces increase pressure in channel A, the control spool reacts against the spring, connecting channel A to TY and allowing excess hydraulic fluid to be discharged into the tank, preventing undue pressure rise. The design includes an external leakage oil discharge via channel TY from the spring chamber.
The DR6DP2-5X/150YV valve can be enhanced with an optional check valve for free flow back from channel A to channel P. Monitoring of secondary pressure is facilitated through a pressure gauge connection. It features several adjustment types including rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale.
This model adheres to porting patterns according to DIN form A and ISO standards with an optional locating hole. It has specified pressure ratings and supports a maximum operating pressure of up to bar and a maximum flow rate of l/min. The component series X signifies its updated series status ensuring reliability and performance in line with current engineering standards.

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.

Notice!
The curve development is maintained if the pressure is set lower according to the pressure rating.
The characteristic curves apply to the pressure at the valve output p = 0 bar across the entire flow range.
