The Bosch Rexroth ZDB10VP2-4X/50 (R900440098) is a high-performance pressure relief valve designed for hydraulic applications requiring precise pressure limitation. This valve is part of the ZDB series and features a sandwich plate design, making it suitable for integration into various hydraulic systems. The ZDB10VP2-4X/50 is engineered to maintain system pressure within desired parameters, ensuring optimal performance and safety. Its construction includes a robust housing and one or two pressure valve cartridges, depending on the application's needs.
This model allows for system pressure adjustments through its adjustment type mechanism, offering flexibility in setting the required pressure levels. In its default state, the valve remains closed until the pressure in channel A surpasses a pre-set threshold adjusted by the spring tension. When this occurs, the pilot poppet activates, allowing hydraulic fluid to flow and reducing the spring-loaded side's pressure. This action causes the spool to move and establish a connection from port A to T (TA), thereby stabilizing the system at the desired pressure.
The ZDB10VP2-4X/50 offers various adjustment options including a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale for precise control over pressure settings. Additionally, it features corrosion protection for enhanced durability in harsh environments.
With its ISO standard porting pattern, this model ensures compatibility with widespread industry practices. It can handle maximum operating pressures up to 350 bar and maximum flow rates of 50 l/min. The Bosch Rexroth ZDB10VP2-4X/50 valve is an essential component for hydraulic circuitry demanding reliable and accurate pressure control.

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.
