The Bosch Rexroth DZ 6 DP1-5X/150XYM/12 (R978879491) is a direct-operated pressure sequence valve designed for efficient pressure-dependent connection of secondary systems. This valve ensures that when the pressure in channel P reaches the set value, it activates the control spool against the compression spring, allowing flow from P to A without pressure drop. The DZ 6 DP1-5X/150XYM/12 receives its control signal either internally from channel P or externally via port BX and features options for both internal and external leakage oil discharge through port TY or via A.
Attention to detail in design allows for an optional check valve to facilitate free hydraulic fluid return from channel A back to channel P, enhancing operational flexibility. Moreover, a pressure gauge connection is available for monitoring sequencing pressure directly at the valve.
The model boasts compatibility with subplate mounting and conforms to DIN form A without a locating hole as standard, while also adhering to ISO with a locating hole for ordering specifics. Subplates are required but must be ordered separately. This model comes with various adjustment types including a rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, or a rotary knob with scale – catering to different user preferences.
The DZ 6 DP1-5X/150XYM/12 operates effectively within its maximum operating pressure of bar and can handle maximum flow rates of l/min. Its component series X signifies its robustness and reliability in operation. The optional presence of a check valve further enhances its utility in diverse hydraulic 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.
