The Bosch Rexroth DZ 6 DP2-5X/210X/12 (R978857401) is a direct operated pressure sequence valve, designed for precise control in hydraulic systems. This model ensures a pressure-dependent connection of a secondary system once the sequencing pressure, set via an adjustable component, is achieved. The control spool of the valve is maintained in its initial position by a compression spring, keeping the valve blocked until the pressure in channel P reaches the set value. At this point, the control spool shifts to allow flow from P to A, activating the connected system without pressure loss.
The DZ 6 DP2-5X/210X/12 model receives its control signal either internally from channel P or externally through port BX. Leakage oil discharge can be managed either externally via port TY or internally through channel A. It's important to note that with internal leakage oil discharge, the set cracking pressure increases with the pressure in channel A.
For systems requiring free hydraulic fluid return flow from channel A back to channel P, an optional check valve can be installed. Additionally, this model features a pressure gauge connection for monitoring sequencing pressure directly at the valve.
This particular Bosch Rexroth valve is engineered for subplate mounting and conforms to DIN form A without locating hole as standard and ISO with locating hole for ordering configurations. Subplates are available separately upon order. It offers various adjustment types including rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale.
The DZ 6 DP2-5X/210X/12 operates at maximum pressures up to bar and supports maximum flow rates of l/min. Its design and capabilities make it suitable for a wide range of industrial applications where reliable and precise sequence control is needed within hydraulic circuits.

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.
