The Bosch Rexroth DZ6DP1-5X/25 (R900401234) is a high-performance direct operated pressure sequence valve designed for precision control in hydraulic systems. This valve is particularly suited for applications where a secondary system needs to be connected in a pressure-dependent manner. The sequencing pressure can be accurately set through various adjustment types, including rotary knobs and threaded pins, ensuring adaptability to specific system requirements.
Constructed with durability and reliability in mind, the DZ6DP1-5X/25 features a compression spring that maintains the control spool in its initial position, causing the valve to remain blocked until the appropriate pressure is reached. Once the set value of the compression spring is met, the spool shifts to allow fluid connection from P to A without any pressure drop, enabling efficient operation of the connected system.
The flexibility of this model extends to its signal reception capabilities; it can receive control signals internally from channel P or externally via port BX. Additionally, it allows for either external or internal leakage oil discharge through port TY or via A, respectively. Users should note that with internal leakage oil discharge, the set cracking pressure will increase by the amount present in channel A.
Moreover, an optional check valve can be installed for unobstructed hydraulic fluid return from channel A back to channel P, enhancing the valve's versatility. Monitoring and maintenance are made convenient with a pressure gauge connection that facilitates sequencing pressure checks directly at the valve.
The DZ6DP1-5X/25 adheres to internationally recognized standards for subplate mounting and offers various porting patterns according to DIN and ISO specifications. Subplates are available as separate orders. This component comes with multiple options for maximum operating pressures and flow rates, making it suitable for diverse hydraulic applications requiring precise sequence control.

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.
