The Bosch Rexroth DZ6DP3-5X/25XY (R900978787) is a direct-operated pressure sequence valve designed for precise control in hydraulic systems. This valve is engineered to facilitate pressure-dependent connection of a second system by setting the sequencing pressure through an adjustable component. The robust construction includes a compression spring that maintains the control spool in its initial position, ensuring that the valve remains blocked until the pressure in channel P reaches the pre-set value.
Upon reaching this set value, the control spool shifts, allowing fluid from P to A and enabling the connected system to function without pressure loss. The DZ6DP3-5X/25XY offers flexibility for control signal reception, either internally from channel P or externally via port BX. Additionally, it features options for leakage oil discharge, which can be executed externally through port TY or internally through A, with attention required as internal discharge influences the cracking pressure by the amount present in channel A.
This model also supports optional installation of a check valve for unimpeded fluid return from A to P and includes a pressure gauge connection for monitoring sequencing pressure directly at the valve. Designed for subplate mounting with porting patterns conforming to DIN form A (standard) or ISO with locating hole (as specified), it requires subplates to be ordered separately.
The DZ6DP3-5X/25XY comes with various adjustment types including rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale—providing versatility for different application requirements. With its maximum operating pressure of up to 315 bar and flow capacity up to 80 l/min, this Bosch Rexroth sequence valve is well-suited for high-performance hydraulic applications where precise pressure control is essential.

Valve type DZ 6 DP is a direct operated pressure sequence valve. It is applied for pressure-dependent connection of a second system. The sequencing pressure is set via the adjustment type (4).
The compression spring (3) holds the control spool (2) in initial position, the valve is blocked. The pressure in channel P is applied via the control line (6) at the spool face of the control spool (2) opposite the compression spring (3).
If the pressure in channel P reaches the set value of the compression spring (3), the control spool (2) is moved to the left and the connection from P to A is opened. The system connected to channel A is connected without a pressure drop in channel P.
The control signal is received internally via the control line (6) from channel P or externally via port B (X).
Depending on the use of the valve, leakage oil discharge is realized externally via port T (Y) or internally via A.
Attention!
With internal leakage oil discharge, the set cracking pressure is increased by the pressure in channel A.
A check valve (5) can be optionally installed for free hydraulic fluid return flow back from channel A to channel P.
A pressure gauge connection (1) enables control of the sequencing pressure at the valve.
