The Bosch Rexroth DZ6DP2-5X/75YV (R900553251) is a high-performance direct operated pressure sequence valve designed for precise pressure-dependent connection of secondary systems. This model features a robust construction that ensures reliable operation and a long service life. The valve operates by utilizing a compression spring that holds the control spool in its initial position, effectively blocking the valve. When the pressure in channel P reaches the preset value of the compression spring, the control spool shifts, opening the connection from P to A and allowing for seamless integration of the system connected to channel A without inducing a pressure drop in channel P.
The DZ6DP2-5X/75YV offers flexible control signal options, receiving internal signals via control line from channel P or externally through port B X. It accommodates different methods of leakage oil discharge, either externally via port T Y or internally through A, with attention required as internal discharge can increase cracking pressure due to channel A's pressure. An optional check valve can be integrated for free hydraulic fluid return from A to P, enhancing functionality.
This model also includes a pressure gauge connection for monitoring sequencing pressure directly at the valve. The DZ6DP2-5X/75YV is designed for subplate mounting with porting patterns conforming to DIN form A or ISO standards with locating hole as per ordering specifications. Subplates are available separately. The valve comes in various sizes and component series X, capable of handling maximum operating pressures up to several hundred bars and maximum flow rates measured in liters per minute.
Adjustment options for this model include a rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale – providing users with versatility according to their operational needs. Optional features such as check valves are available upon request to cater to specific application requirements.

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.
