The Bosch Rexroth DZ6DP3-5X/75Y (R900478933) is a direct operated pressure sequence valve designed for the precise control of hydraulic systems. This model facilitates the pressure-dependent connection of a second system by setting the sequencing pressure through its adjustable configuration. The valve features a compression spring that maintains the control spool in a blocked initial position, ensuring that the valve remains closed until the pressure in channel P reaches a pre-determined level set by the spring.
Once this pressure threshold is met, the control spool shifts, allowing fluid to flow from P to A without inducing a pressure drop in channel P. The DZ6DP3-5X/75Y can receive control signals either internally from channel P or externally via port BX. It also offers flexibility in managing leakage oil discharge, which can be directed externally through port TY or internally through A. Users should note that internal leakage oil discharge will affect the set cracking pressure due to additional pressure in channel A.
An optional check valve can be installed to enable free return flow of hydraulic fluid from channel A back to channel P, enhancing the valve's versatility. Additionally, there's an integrated pressure gauge connection for monitoring sequencing pressure directly at the valve.
The DZ6DP3-5X/75Y is designed for subplate mounting and complies with DIN form A porting pattern standards without a locating hole and ISO standards with a locating hole. Subplates are available as separate orders. The maximum operating pressure for this component series X is specified by Bosch Rexroth's standard parameters, as well as its maximum flow rate measured in liters per minute (l/min). Adjustment options include various types of rotary knobs and threaded pins to suit different operational preferences and requirements, with some models featuring scales or locks for added precision and security.

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.
