The Bosch Rexroth DZ6DP7-5X/25 (R901114999) is a direct operated pressure sequence valve designed to facilitate the pressure-dependent connection of a secondary system. This valve is characterized by its precision in maintaining the set sequencing pressure, which is adjustable via an external mechanism. The compression spring within the valve ensures that the control spool remains in its initial position, keeping the valve closed until the pressure in channel P reaches the predetermined value. Once this occurs, the spool shifts, allowing for an open connection from P to A without any loss of pressure in channel P.
The DZ6DP7-5X/25 model offers versatility through its internal or external control signal options, obtained either from channel P directly or via port BX. The method of leakage oil discharge can be chosen based on application needs; it can be directed externally through port TY or internally through A. However, it's important to note that internal leakage oil discharge will result in an increased cracking pressure due to the presence of pressure in channel A.
An optional check valve can be integrated into the system for unimpeded hydraulic fluid return from channel A back to P. Additionally, a pressure gauge connection is available for monitoring sequencing pressure directly at the valve. This model adheres to standard porting patterns according to DIN form A without a locating hole and ISO with a locating hole for subplate mounting.
The DZ6DP7-5X/25 comes with various options for adjustment types including rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale. The size and component series X of this model indicate its capability to withstand maximum operating pressures up to bar and handle maximum flow rates measured in liters per minute. Subplates are required for this model and must be ordered separately.

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.
