The Bosch Rexroth DZ6DP2-5X/75V (R900425809) is a high-precision, direct operated pressure sequence valve designed for efficient control in hydraulic systems. This valve is specifically engineered to facilitate the pressure-dependent connection of a second system by setting the sequencing pressure via an adjustable component. The robust design includes a compression spring that maintains the control spool in its initial position, ensuring that the valve remains blocked until the desired pressure threshold is reached.
As pressure in channel P increases to match the predetermined value of the compression spring, the control spool shifts, thereby opening the connection from P to A and allowing for seamless integration of the secondary system without any drop in channel P's pressure. The DZ6DP2-5X/75V can receive a control signal either internally from channel P or externally via port BX, offering versatility in application.
Leakage oil discharge with this unit can be managed either externally through port TY or internally via port A, depending on user requirements. However, users should note that internal leakage oil discharge will result in an increased set cracking pressure due to channel A's pressure. An optional check valve can be integrated for unobstructed hydraulic fluid return from channel A back to P, enhancing operational flexibility.
Additionally, this model includes a pressure gauge connection for monitoring sequencing pressure directly at the valve. Designed for subplate mounting and conforming to DIN form A standards without a locating hole as default (and ISO with locating hole upon request), it offers various optional adjustment types such as rotary knob and lockable rotary knob with scale among others.
The Bosch Rexroth DZ6DP2-5X/75V boasts impressive specifications including multiple component series X maximum operating pressures and flow rates. Subplates for this model are available by separate order. This precision-engineered valve stands out for its reliability and adaptability across different hydraulic applications.

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.
