The Bosch Rexroth DB 10 K3-4X/315YV (R900438124) is a high-performance screw-in cartridge valve designed to function as a pilot-operated pressure relief valve for block design installation, primarily used for system pressure limitation. This valve belongs to the DB.K product family classification and is identified by its ability to handle a maximum operating pressure of 315 bar (4568 psi) and a maximum flow of up to NG10 l/min. It features an Mx cavity and utilizes FKM as its sealing material, ensuring reliable performance under various conditions.
The DB 10 K3-4X/315YV valve's capabilities include an internal pilot oil supply and external pilot oil return, with a poppet-type spool that responds to changes in system pressure. The adjustment options for this model include a lockable rotary knob with scale, allowing precise control over the system pressure settings.
Designed with pilot-operated functionality, this relief valve maintains the desired pressure level by opening the connection from main port A to B when the set value is exceeded. The counter pressures at main port A are considered in setting the system pressure, contributing to the valve's efficiency and safety in operation.
Compatible with hydraulic fluids such as HL, HLP, HEES, and HEPG, the Bosch Rexroth DB 10 K3-4X/315YV ensures versatility across various hydraulic applications while maintaining superior quality standards synonymous with Bosch Rexroth's engineering expertise. The product's robust construction and reliability make it suitable for demanding applications where precise pressure control is essential.

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.
