The Bosch Rexroth DB 10 K2-4X/315YV (R900438126) is a high-performance, pilot-operated pressure relief valve designed for screw-in cartridge valve systems. This model is engineered to maintain system pressure within safe limits and to act as a system pressure limitation device. The valve has a maximum operating pressure of 315 bar (4568 psi) and can accommodate a maximum flow rate of 120 l/min (31.7 gpm), ensuring efficient operation in various hydraulic applications.
The DB 10 K2-4X/315YV features a poppet-type spool that ensures reliable and stable operation. It is designed with an internal pilot oil supply and an external pilot oil return, which contribute to the proper functioning of the valve by allowing for precise control over system pressure. The adjustment options available for this model include a sleeve with hexagon and protective cap, which allows users to set the desired pressure level securely.
Constructed to fit Cavity Mx, this relief valve from Bosch Rexroth's DB.K product family showcases exceptional build quality with FKM sealing material, ensuring durability and resistance against various hydraulic fluids such as HL, HLP, HEES, and HEPG. The unit's weight further attests to its robust construction.
With its direct pilot operation, the DB 10 K2-4X/315YV ensures that any excess pressure is quickly relieved by allowing fluid to flow from the main port through the system when it exceeds the set value at spring. This mechanism helps prevent potential damage due to overpressure conditions.
Overall, the Bosch Rexroth DB 10 K2-4X/315YV offers reliable performance in controlling hydraulic system pressure and is suitable for applications requiring precise pressure relief capabilities within its specified operational parameters.

Pressure valves type DB..K.. are pilot-operated pressure relief valves for block design installation. They are used for system pressure limitation. The system pressure can be set via the adjustment type (4).
In the initial position the valves are closed. The pressure in main port 1 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 main port 1 exceeds the value set at spring (5), the pilot poppet (6) opens. Hydraulic fluid flows from the spring-loaded side of the spool (1) via nozzle (3) and channel (7) into the main port 3. The resulting pressure drop moves the spool (1) and thus opens the connection from main port 1 to 2 while maintaining the pressure set at spring (5).
Die pilot oil return from the two spring chambers is effected externally, via main port 3.
Notice!
Counter pressures (main port 3) add up to the set pressure.
