The Bosch Rexroth DZ 6 DP2-5X/210Y/12 (R978862835) is a direct operated pressure sequence valve designed to enable pressure-dependent connection of a second system by setting the sequencing pressure through an adjustable type. This valve operates by using a compression spring that holds the control spool in its initial position, ensuring the valve remains blocked until the pressure in channel P reaches the set value. Once this set value is achieved, the control spool moves, creating an open connection from P to A, allowing for system engagement without pressure drop. The DZ 6 DP2-5X/210Y/12 features internal or external control signal reception and has options for leakage oil discharge either externally via port T Y or internally through A. An important note for users is that with internal leakage oil discharge, the set cracking pressure will increase due to the pressure in channel A. This model may be equipped with an optional check valve for free hydraulic fluid return from channel A to P, enhancing its versatility. Additionally, it includes a pressure gauge connection to monitor sequencing pressure directly at the valve. Designed for subplate mounting with porting patterns conforming to DIN form A (without locating hole) and ISO (with locating hole), this valve requires subplates ordered separately. It offers various adjustment types such as a rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, and a rotary knob with scale. The DZ 6 DP2-5X/210Y/12 can also be optionally fitted with a check valve. With its maximum operating pressure and flow capacity specified by component series X standards, this Bosch Rexroth sequence valve ensures reliable performance in controlling hydraulic system pressures.

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.
