The Bosch Rexroth DZ6DP1-5X/75M/12 (R900923289) is a direct-operated pressure sequence valve designed to enable pressure-dependent connection of a secondary system. This valve is distinguished by its precision in maintaining the sequencing pressure, which is set through an adjustment type. A key feature of the DZ6DP1-5X/75M/12 is its internal compression spring, which holds the control spool in its initial position, ensuring that the valve remains blocked until the appropriate pressure threshold is met.
When the pressure in channel P reaches the preset value of the compression spring, the control spool shifts, allowing for an open connection from P to A without causing a drop in channel P's pressure. This feature ensures that any system connected to channel A engages seamlessly. The control signal for this operation can be sourced either internally from channel P or externally via port B X.
The valve's design also accounts for leakage oil discharge, which can be managed externally through port T Y or internally via A. However, users should note that internal leakage oil discharge will affect the set cracking pressure due to additional pressure in channel A. An optional check valve can be installed to facilitate free hydraulic fluid return flow from A back to P, enhancing operational flexibility.
For monitoring purposes, a pressure gauge connection is available for checking sequencing pressure directly at the valve. The DZ6DP1-5X/75M/12 comes with options for subplate mounting with porting patterns conforming to DIN form A standards or ISO with locating holes. Subplates are ordered separately.
This model supports various operating pressures and flow rates and offers different adjustment types such as rotary knobs (both standard and lockable with scale), threaded pins with hexagon and protective cap, and an optional check valve. Its size and component series X denote its capacity to handle maximum operating pressures and flow rates effectively within specified limits.

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.
