The Bosch Rexroth DZ 6 DP1-5X/25/12 (R978892469) is a direct-operated pressure sequence valve designed for the precise control of hydraulic systems. This high-quality component ensures a pressure-dependent connection of a second system by setting the sequencing pressure through various adjustment types. The compression spring within the valve maintains the control spool in its initial position, ensuring that the valve remains blocked until the pressure in channel P reaches a pre-set value. At this point, the spool moves to allow flow from P to A, enabling the connected system to operate without pressure drop.
The DZ 6 DP1-5X/25/12 offers versatile control signal options, receiving signals either internally from channel P or externally via port BX. It also provides flexibility in handling leakage oil discharge, which can be executed externally through port TY or internally via A. This feature is critical because internal leakage oil discharge affects the set cracking pressure due to channel A's influence.
An optional check valve can be integrated into the design for unidirectional free flow from A back to P, enhancing operational efficiency and fluid control. Additionally, a pressure gauge connection is available for monitoring sequencing pressure directly at the valve.
This model is suitable for subplate mounting with porting patterns that align with DIN form A (standard) and ISO standards with locating holes. Customers can specify their requirements when ordering subplates separately. The DZ 6 DP1-5X/25/12 supports various adjustment types such as rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, and check valves as per application needs.
With its robust design and multiple configuration options, this Bosch Rexroth sequence valve stands out for its reliability and adaptability in controlling hydraulic system pressures up to its maximum operating parameters of X component series maximum operating pressure (bar) and maximum flow (l/min).

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.
