The Bosch Rexroth DZ6DP1-5X/150X (R900431526) is a direct operated pressure sequence valve designed for the precise control of hydraulic systems. This model ensures a pressure-dependent connection of a secondary system by setting the sequencing pressure through an adjustable type. The valve features a compression spring that maintains the control spool in its initial position, causing the valve to be blocked until the pressure in channel P reaches the set value. Once this occurs, the spool moves to allow connectivity from P to A without any loss of pressure.
The DZ6DP1-5X/150X model receives its control signal either internally from channel P or externally via port BX. It also offers flexibility in terms of leakage oil discharge, which can be directed externally through port TY or internally via A, depending on specific application requirements. However, it is important to note that with internal leakage oil discharge, the set cracking pressure will increase due to the pressure in channel A.
Additionally, this valve can be optionally fitted with a check valve to enable free return flow of hydraulic fluid from channel A back to channel P. Monitoring and controlling sequencing pressure is straightforward thanks to a dedicated pressure gauge connection on the valve itself.
This particular model is designed for subplate mounting and adheres to standard porting patterns according to DIN form A without locating hole or ISO standards with locating hole as per ordering specifications. Subplates are required but must be ordered separately. The DZ6DP1-5X/150X offers various adjustment types including rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale for versatile application across different settings.
In terms of size and performance capabilities, it operates at a maximum pressure of up to 315 bar and allows for maximum flow rates as specified by Bosch Rexroth standards. Optional features such as check valves are available for enhanced functionality tailored to specific operational needs.

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.
