The Bosch Rexroth DZ 6 DP1-5X/150X/12 (R978023027) is a high-performance direct-operated pressure sequence valve designed to enable a pressure-dependent connection of a secondary system. This valve operates by utilizing an adjustable compression spring to set the sequencing pressure, which holds the control spool in its initial position, thereby blocking the valve. When the pressure in channel P reaches the set value, the control spool is actuated, creating an open connection from P to A without any pressure drop, allowing for efficient operation of the connected system.
The DZ 6 DP1-5X/150X/12 features an internal control signal that can be received from channel P or externally through port B X. The design allows for leakage oil discharge either externally via port T Y or internally through A. It is important to note that with internal leakage oil discharge, the cracking pressure setting will increase by the pressure present in channel A.
An optional check valve can be installed to facilitate free return flow of hydraulic fluid from channel A back to channel P. Additionally, a pressure gauge connection is available for monitoring sequencing pressure directly at the valve.
This model is designed for subplate mounting with porting patterns conforming to DIN form A standards without a locating hole and ISO with a locating hole. Subplates are available as separate orders. The valve offers various adjustment types including rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale. Options also include an adjustable check valve.
With its robust design, this Bosch Rexroth sequence valve is suitable for applications requiring precise control of hydraulic systems and can handle maximum operating pressures up to bar and maximum flow rates expressed in liters per minute as specified by its component series X designation.

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.
