The Bosch Rexroth DZ 6 DP2-5X/210M/12 (R978876699) is a high-performance direct operated pressure sequence valve designed for efficient control in hydraulic systems. This valve model is engineered to facilitate the pressure-dependent connection of a secondary system by setting the sequencing pressure through an adjustable mechanism. The robust construction includes a compression spring that maintains the control spool in its initial position, causing the valve to remain blocked until the pressure in channel P reaches the predetermined threshold set by the spring.
Once this pressure level is achieved, the control spool shifts, allowing fluid communication from P to A and enabling the connected system to operate without any drop in channel P's pressure. Users have flexibility with this model, as it accepts control signals both internally from channel P and externally via port B X. The design also accommodates different methods of leakage oil discharge—either externally through port T Y or internally via A—though it's important to note that internal discharge will affect the set cracking pressure due to channel A's influence.
For added versatility, an optional check valve can be integrated into the system for unimpeded hydraulic fluid return from A back to P. Monitoring and adjustments are made straightforward with a pressure gauge connection for checking sequencing pressure and various adjustment types available including a rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, or a plain rotary knob with scale.
This Bosch Rexroth valve is intended for subplate mounting and adheres to standard DIN form A without a locating hole or ISO with a locating hole for porting patterns. Customers must order subplates separately if needed. With its wide range of customization options and robust design ensuring reliable operation under maximum operating pressures and flow rates, this model stands out as an essential component for sophisticated hydraulic applications.

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.
