The Bosch Rexroth DZ10DP2-4X/75M (R900579596) is a high-performance industrial hydraulic valve designed for reliable pressure sequencing. This mechanically actuated spool valve is directly operated and features a spool symbol A B, ensuring efficient control of hydraulic systems. It is capable of handling a maximum pressure as indicated in its product specifications, with precise settings for operation.
The valve boasts multiple ports and mechanical actuation, with subplate mounting for secure installation. The connection diagram adheres to ISO standards, ensuring compatibility and ease of integration into various hydraulic systems. The DZ10DP2-4X/75M can accommodate a significant max flow rate and comes with NBR seals that are compatible with a range of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC.
The design includes an internal compression spring that maintains the control spool in its initial position until the pressure in channel A reaches the set value. At this point, the spool moves to allow fluid connection from A to B without pressure drop. The control signal can be received either internally from channel A or externally via port X.
Leakage oil discharge can be managed either externally through port Y or internally through B. An optional check valve allows free return flow from channel B to A. Additionally, a pressure gauge connection is available for monitoring sequencing pressure directly at the valve.
This valve comes in various adjustment types including rotary knob and threaded pin configurations—some options come equipped with protective caps or scales for precise adjustments. The maximum operating pressure and flow rate are determined by the specific component series and size of the valve.

Valve type DZ 10 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 (1).
The compression spring (2) holds the control spool (3) in initial position, the valve is blocked. The pressure in channel A is applied via the control line (4) at the spool face of the control spool (3) opposite the compression spring (2).
If the pressure in channel A reaches the set value of the compression spring (2), the control spool (3) is moved to the right and the connection from A to B is opened. The system connected to channel B is connected without a pressure drop in channel A.
The control signal is received internally via the control line (4) from channel A or externally via port X.
Depending on the use of the valve, leakage oil discharge is realized externally via port Y or internally via B.
Attention!
With internal leakage oil discharge, the set cracking pressure is increased by the pressure in channel B.
A check valve (5) can be optionally installed for free hydraulic fluid return flow from channel B to channel A.
A pressure gauge connection (6) enables control of the sequencing pressure at the valve.
