The Bosch Rexroth DZ10DP7-4X/75 (R900964542) is a high-performance direct operated pressure sequence valve designed for efficient control in hydraulic systems. This valve ensures a pressure-dependent connection of a second system, with the sequencing pressure easily set through an adjustable mechanism. The robust construction includes a compression spring that maintains the control spool in its initial position, effectively blocking the valve until the preset pressure level is reached. When the pressure in channel A attains this set value, it overcomes the compression spring force, shifting the control spool to enable flow from A to B. This operation guarantees that there is no pressure drop in channel A when connecting to system B. Users have the flexibility of receiving control signals either internally from channel A or externally via port X. The DZ10DP7-4X/75 valve offers options for leakage oil discharge which can be directed externally through port Y or internally through channel B. However, it's important to note that internal leakage oil discharge will result in an increase in the set cracking pressure due to the pressure present in channel B. An optional check valve feature is available for facilitating free hydraulic fluid return from channel B back to channel A, enhancing versatility. Additionally, there's a provision for connecting a pressure gauge directly to the valve for monitoring sequencing pressures accurately and conveniently. This model comes prepared for subplate mounting and conforms with ISO porting patterns. It offers diverse adjustment types including rotary knobs and threaded pins with protective caps, some of which come with scales or are lockable for additional security and precision. With its capability to handle maximum operating pressures and flow rates efficiently, this Bosch Rexroth sequence valve stands out as an essential component for advanced hydraulic applications where reliable performance and precise control are paramount.

Valve type DZ 10 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 (1).

The compression spring (2) holds the control spool (3) in initial position, the valve is blocked. The pressure in channel A is applied via the control line (4) at the spool face of the control spool (3) opposite the compression spring (2).

If the pressure in channel A reaches the set value of the compression spring (2), the control spool (3) is moved to the right and the connection from A to B is opened. The system connected to channel B is connected without a pressure drop in channel A.

The control signal is received internally via the control line (4) from channel A or externally via port X.

Depending on the use of the valve, leakage oil discharge is realized externally via port Y or internally via B.

Attention!

With internal leakage oil discharge, the set cracking pressure is increased by the pressure in channel B.

A check valve (5) can be optionally installed for free hydraulic fluid return flow from channel B to channel A.

A pressure gauge connection (6) enables control of the sequencing pressure at the valve.
