The Bosch Rexroth DZ 6 DP2-5X/25XY/12 (R978859027) is a direct operated pressure sequence valve designed for precise control in hydraulic systems. This model serves to connect a secondary system in a pressure-dependent manner, with the transition point determined by an adjustable sequencing pressure. The valve employs a compression spring that maintains the control spool in its initial position, ensuring that the valve remains blocked until the pressure in channel P exceeds the spring's set value. Once this occurs, the spool shifts to allow fluid flow from P to A without loss of pressure in channel P.
The DZ 6 DP2-5X/25XY/12 enables internal or external control signal reception and offers options for leakage oil discharge either externally via port T Y or internally through A. This flexibility ensures that it can cater to various system requirements and configurations. Additionally, this model can be optionally fitted with a check valve to allow free return flow of hydraulic fluid from A back to P.
For monitoring purposes, there's a provision for a pressure gauge connection which facilitates checking of the sequencing pressure directly at the valve. The DZ 6 DP2-5X/25XY/12 is designed for subplate mounting with porting patterns conforming to DIN form A standards without locating holes and ISO patterns with locating holes.
This product comes in various sizes and component series X, each supporting different maximum operating pressures and flow rates. Users can select from multiple adjustment types according to their needs, including rotary knobs (with or without scales), threaded pins with hexagon and protective caps, or lockable rotary knobs with scales. Subplates are required but must be ordered separately.
In summary, Bosch Rexroth's DZ 6 DP2-5X/25XY/12 is a versatile and reliable component suitable for complex hydraulic systems requiring precise sequence control of pressures and flows.

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.
