The Bosch Rexroth ZDB10DB2-2X/100V (R901439548) is a direct operated pressure relief valve designed for hydraulic system applications where reliable pressure regulation is essential. This model is part of the ZDB series and comes in a sandwich plate design, which allows for easy installation within a range of hydraulic systems. The valve consists of a housing with seat and control spool, allowing for precise control over system pressure via an adjustment type mechanism. This particular model is engineered to remain closed in its default state, safeguarding hydraulic systems from the risks associated with excessive pressures. It features rapid and quiet operation with minimal leakage due to its seat design that offers resistance to oil contamination. The integrated damping feature of the control spool ensures stable performance and manages the pressure increase as flow rates rise. Upon delivery, the ZDB10DB2-2X/100V valve is set to the lowest possible pressure setting. It operates by responding to system pressure at channel P; when this pressure surpasses the preset value, the control spool activates, allowing fluid to flow from channel P to channel T (referred to as TA and TB in this product's documentation), thus maintaining system pressure at safe levels. For enhanced monitoring capabilities, there's an MP version that allows for system pressure tracking through a measuring port. This feature can be crucial for applications requiring precise pressure management. The ZDB10DB2-2X/100V offers various customization options including different adjustment types like spindle with hexagon, rotary knob, or lockable rotary knob with scale; it also provides circuit options and can come in a corrosion-protected design if needed. It adheres to ISO porting patterns for compatibility and offers selectable pressure ratings. The maximum operating pressure for this unit is specified by Bosch Rexroth standards, along with its maximum flow rate capacity in liters per minute (l/min), ensuring it meets specific application requirements efficiently and effectively.

Industrial hydraulic valve in a high performance range. Reliable pressure limitation to setting value
Unpacked Weight: 2.680 kg
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)
