The Bosch Rexroth DZ 6 DP2-5X/150X/12 (R978871683) is a direct operated pressure sequence valve designed for the precise control of hydraulic systems. It functions by allowing a secondary system to connect based on the pressure set via its adjustable control. The valve utilizes a compression spring to maintain the control spool in its initial blocked position until the pressure in channel P meets the predetermined value, at which point the spool shifts, permitting flow from P to A without pressure drop.
This model is equipped with an internal control signal that can be received either from channel P or externally via port BX. The valve also offers flexibility in handling leakage oil discharge, which can be managed externally through port TY or internally through A. The potential installation of a check valve allows for free return flow of hydraulic fluid from A to P, enhancing the valve's application scope.
For monitoring purposes, a pressure gauge connection is provided for checking sequencing pressure directly at the valve. The DZ 6 DP2-5X/150X/12 is designed for subplate mounting and adheres to DIN form A (without locating hole) and ISO standards (with locating hole) for porting patterns. Customers should note that subplates must be ordered separately.
The valve comes in various sizes and component series X, with maximum operating pressures up to bar and maximum flow rates measured in liters per minute (l/min). Users have several adjustment options including a rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, or simply a rotary knob with scale. For those requiring it, an optional check valve can be installed.
Overall, this Bosch Rexroth pressure sequence valve stands as a reliable component for sophisticated hydraulic system operations where precise pressure sequencing is critical.

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.
