The Bosch Rexroth DZ6DP2-5X/25XYV (R900949200) is a direct operated pressure sequence valve designed to facilitate the pressure-dependent connection of a second hydraulic system. This valve operates by utilizing a compression spring to hold the control spool in an initial position, effectively blocking flow. Pressure in channel P is applied against the spool, and once it overcomes the set value of the spring, the spool moves to allow fluid from P to A, engaging the second system without impacting pressure in channel P.
The DZ6DP2-5X/25XYV can receive control signals either internally from channel P or externally via port BX. The choice between internal or external leakage oil discharge is provided through port TY or internally via A, with an important note that internal discharge will affect the set cracking pressure due to additional pressure in channel A. An optional check valve can be integrated for free return flow from A to P.
For monitoring purposes, a pressure gauge connection is available for checking sequencing pressure directly at the valve. The DZ6DP2-5X/25XYV valve comes with several options for subplate mounting and conforms to DIN form A standards without a locating hole as default, or ISO standards with a locating hole if specified.
Additionally, this model offers various adjustment types including a rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale. The maximum operating pressure for this component is determined by its series X designation and it supports a maximum flow measured in liters per minute (l/min). Subplates are required for mounting but must be ordered separately. The presence of optional features like check valves enhances its adaptability for different hydraulic circuit configurations.

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.
