The Bosch Rexroth DZ 6 DP2-5X/75M/12 (R978930335) is a direct operated pressure sequence valve designed for the pressure-dependent connection of a second system. This valve operates by utilizing a compression spring to hold the control spool in its initial position, effectively blocking the valve. Pressure from channel P is applied at the spool face opposite the spring, and once this pressure reaches the spring's set value, the control spool moves to allow flow from P to A, thereby enabling the connected system without pressure drop in channel P.
The DZ 6 DP2-5X/75M/12 model features an internal or external control signal option via port B X and allows for either external leakage oil discharge through port T Y or internal via A. Users should be aware that with internal leakage oil discharge, the set cracking pressure increases with the pressure in channel A. An optional check valve can be installed for free hydraulic fluid return from channel A back to channel P.
Additionally, this valve includes a pressure gauge connection for monitoring sequencing pressure directly at the unit. It is designed for subplate mounting and adheres to DIN form A without a locating hole as standard, and ISO form with a locating hole for specific ordering information. Subplates are ordered separately. The DZ 6 DP2-5X/75M/12 offers various adjustment types including rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale; it also has an optional check valve.
This Bosch Rexroth valve has a maximum operating pressure of up to bar and can handle maximum flow rates of l/min. Its size and component series X reflect its robust capacity for managing hydraulic flow within a wide range of 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.
