The Bosch Rexroth ZDB10DP2-2X/50V (R901438981) is a direct operated pressure relief valve designed for hydraulic system protection. This sandwich plate valve is part of the ZDB series, which is known for its quick and quiet operation with virtually no leakage. It features a housing with seat and control spool, where the system pressure can be adjusted to the desired level. The valve remains closed in its resting state, safeguarding hydraulic systems from excessive pressures.
The ZDB10DP2-2X/50V responds to pressure changes swiftly, maintaining stability due to the integrated damping within the control spool. This design element also contributes to a minimal pressure increase when flow rates rise. Resistant to oil contamination thanks to its seat design, this valve ensures consistent and reliable performance.
In its default state upon delivery, the valve is set at the lowest possible pressure setting. When in operation, if system pressure surpasses the set value, the control spool opens allowing fluid to flow from channel P to T (TA or TB as referred in this data sheet), thereby limiting system pressure within safe parameters.
For models like MP, system pressure settings can be monitored via a measuring port that accommodates a pressure load cell. The ZDB10DP2-2X/50V offers various options such as spindle with hexagon, rotary knob or lockable rotary knob with scale for adjustment types; and it comes in corrosion-protected designs for enhanced durability.
This model adheres to ISO porting pattern standards and offers different circuit options. It has a maximum operating pressure of up to 315 bar and can handle maximum flow rates as indicated by specific size and component series requirements. The Bosch Rexroth ZDB10DP2-2X/50V stands out for its precise control capabilities in hydraulic applications where maintaining consistent system pressures is critical for optimal machinery function and safety.

Pressure valves of type ZDB10D and Z2DB10D are direct operated pressure relief valves in sandwich plate design.
The valves basically consist of housing (1) with seat (2) and control spool (3). The system pressure is set via the adjustment type (4).
The valves are closed in their rest position and protect a hydraulic system and its components against excessive pressures.
These valves respond quickly, noiselessly and in a virtually leakage-free manner. Thanks to the seat design, they are resistant against oil contamination. The integrated damping of the control spool (3) ensures extremely stable behavior and a low pressure increase with increasing flow.
In the state as delivered, the valves are set to the minimum possible pressure. The system pressure applied to channel P acts on the control spool (3). If the system pressure increases above the set value, the control spool (3) opens and the hydraulic fluid flows from channel P in channel T. This limits the system pressure to the set value.
For version “MP”, the set system pressure can be recorded and monitored using a pressure load cell at the measuring port (5) (see dimensions)
