The Bosch Rexroth DZ 6 DP3-5X/210XYM/12 (R978917225) is a direct operated pressure sequence valve designed to enable pressure-dependent connection of a second system. This model operates by utilizing a compression spring that holds the control spool in its initial position, thereby blocking the valve. When the pressure in channel P meets the set value of the compression spring, the control spool is actuated, allowing flow from P to A and connecting the secondary system without pressure drop.
The DZ 6 DP3-5X/210XYM/12 receives its control signal internally from channel P or externally via port BX. It offers flexibility in managing leakage oil discharge, which can be executed externally through port TY or internally via A. Users should be aware that with internal leakage oil discharge, the set cracking pressure increases due to channel A's pressure.
An optional check valve can be installed for free return flow of hydraulic fluid from channel A back to channel P. Additionally, a pressure gauge connection is available for monitoring sequencing pressure at the valve itself. The model accommodates subplate mounting with a porting pattern conforming to DIN form A without locating hole as standard or ISO with locating hole based on ordering specifications. Subplates are ordered separately.
The DZ 6 DP3-5X/210XYM/12 provides various options for adjustment types including rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale. Users can select these options based on their specific needs and preferences.
This particular model has a size component series X and can withstand a maximum operating pressure (bar) and maximum flow (l/min) as defined by its specifications. The versatility of this Bosch Rexroth valve makes it suitable for applications requiring precise control over sequencing pressures and flows within hydraulic systems.

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.
