The Bosch Rexroth DZ10DP3-4X/210YM (R901191686) is a high-performance, direct-operated pressure sequence valve designed for precise control in hydraulic systems. It functions by enabling the pressure-dependent connection of a second system once a set sequencing pressure is reached. The valve's operation is governed by an adjustable compression spring that holds the control spool in its initial position, effectively blocking flow until the pressure in channel A meets the predefined threshold set via the adjustment type. Upon reaching the set sequencing pressure, the control spool shifts to allow fluid connection from A to B without inducing a pressure drop in channel A. This allows for efficient operation of the system connected to channel B. The control signal for this valve can either be internally received from channel A or externally through port X, providing flexibility in application. The DZ10DP3-4X/210YM offers options for managing leakage oil through either external discharge via port Y or internal discharge via B, with considerations for changes in cracking pressure due to internal discharge conditions. An optional check valve can be integrated into the design for unidirectional free flow of hydraulic fluid from B back to A when necessary. For monitoring and maintenance purposes, a pressure gauge connection is available to check sequencing pressure directly at the valve. This model adheres to ISO standards for subplate mounting and features various adjustment types including rotary knobs (with or without scale), threaded pins with hexagon and protective cap, and lockable rotary knobs with scale. With its robust construction and precise control capabilities, this valve is suitable for applications requiring reliable sequence operation under maximum operating pressures and flows as defined by its product specifications.
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.
