The Bosch Rexroth ZDB10VA3-4X/315V (R900589823) is a pilot-operated pressure relief valve designed for sandwich plate mounting, providing efficient system pressure limitation. This valve is characterized by its robust housing and one or two pressure valve cartridges, which work together to maintain the desired system pressure through an adjustable mechanism. The ZDB10VA3-4X/315V operates in a normally closed position, with the spool being actuated when the pressure in channel A exceeds the preset value on the spring.
The intricate design allows for precise control as hydraulic fluid is redirected from the spring-loaded side of the spool through nozzles, causing a shift in the spool that opens up a pathway from port A to T (TA), thereby stabilizing the pressure at a preconfigured level. The versatility of this model is evident in its multiple adjustment types for setting system pressure, including options such as a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale.
This valve demonstrates exceptional durability and resistance to corrosion, making it suitable for various applications. It conforms to ISO standard porting patterns and offers different circuit options for integration into hydraulic systems. With its ability to handle maximum operating pressures of up to 315 bar and maximum flow rates as specified by Bosch Rexroth's standards, this valve ensures reliable performance in controlling system pressures across diverse operational scenarios. The ZDB10VA3-4X/315V's sandwich plate design simplifies installation while maintaining a compact footprint within hydraulic circuits.

Pressure valves of type ZDB and Z2DB are pilot-operated pressure relief valves in sandwich plate design. They are used for limiting a system pressure. The valves basically consist of the housing (7) and one or two pressure valve cartridges. The system pressure can be set via the adjustment type (4).
In the initial position the valves are closed. The pressure in channel A acts on the spool (1). At the same time, pressure is applied to the spring-loaded side of the spool (1) via nozzle (2) and to the pilot poppet (6) via nozzle (3).
If the pressure in channel A exceeds the value set at the spring (5), the pilot poppet (6) opens. Hydraulic fluid flows from the spring-loaded side of the spool (1), nozzle (3) and channel (8) into channel T (TA). The resulting pressure drop moves the spool (1) and opens the connection from A to T (TA). In channel A, the pressure set at the spring (5) settles.
