The Bosch Rexroth ZDB6DB2-2X/350V (R901423490) is a high-performance industrial hydraulic valve designed for reliable pressure relief at set values. This direct-actuated valve features a spool symbol B T and is capable of handling a maximum pressure as specified in its product group ID. It comes with a number of ports and mechanical actuation, ensuring precise control over hydraulic systems.
With a maximum flow rate as indicated, the ZDB6DB2-2X/350V is suitable for various types of connections, including interim assembly and complies with NFPA T.. R D Size CETOP D and ISO connection diagrams. This valve offers multiple switching positions and has a weight that reflects its robust construction. The seals are made from FKM, making the valve compatible with a wide range of hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR.
Pressure valves like the ZDB6DB2-2X/350V are known for their quick response time and virtually leakage-free operation. The seat design provides resistance against oil contamination while the integrated damping of the control spool ensures stable behavior and minimal pressure increase with rising flow rates. These valves come preset to the minimum possible pressure but can be adjusted to meet specific system requirements.
The sandwich plate design allows for easy integration into hydraulic systems while protecting components from excessive pressures. Additional features include various adjustment types such as spindle with hexagon or rotary knob (lockable or non-lockable), circuit options, and a corrosion-protected design.
This Bosch Rexroth valve is also equipped to accommodate monitoring capabilities via a pressure load cell at the measuring port for certain versions (MP, MA, MB), ensuring operational safety and performance reliability. With its robust design criteria and versatile application potential, this valve stands out as an essential component in advanced hydraulic systems.

Pressure valves of type ZDB6D and Z2DB6D 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,
as well as 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 versions “MP”, “MA” and “MB”, the set system pressure can be recorded and monitored using a pressure load cell at the measuring port (5) (see dimensions)
