The Bosch Rexroth DZ10DP2-4X/210M (R900525300) is a high-performance industrial hydraulic valve designed for reliable pressure sequencing and control. This mechanically actuated spool valve is direct operated, with a spool symbol A B, ensuring precise operation for a variety of applications. It is capable of handling a maximum pressure as defined by the product's specifications, and it features multiple ports for versatile connectivity. The DZ10DP2-4X/210M valve operates by utilizing a compression spring that maintains the control spool in its initial blocked position. When pressure in channel A reaches the set value, the control spool shifts to enable flow from A to B without causing pressure drop in channel A. The sequencing pressure can be adjusted through various means including a rotary knob or threaded pin with hexagon and protective cap. This model offers flexibility with internal or external control signal options and leakage oil discharge that can be managed externally via port Y or internally via B. The potential increase in set cracking pressure due to internal leakage oil discharge is something users should be aware of when configuring their system. Optional features include a check valve for free return flow from channel B to A and a pressure gauge connection for monitoring sequencing pressure directly at the valve. Designed for subplate mounting, it adheres to ISO porting patterns and comes with different adjustment types to cater to user preferences. The Bosch Rexroth DZ10DP2-4X/210M valve is suitable for use with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC as indicated by its NBR seals. With its robust construction and precise operational capabilities, this valve stands out as an essential component in advanced hydraulic systems requiring dependable performance under varying conditions.

Industrial hydraulic valve in a high performance range. Reliable pressure sequencing to setting.
Unpacked Weight: 3.16 kg
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.
