The Bosch Rexroth DB 10 K1-4X/315YV (R900438122) is a high-quality screw-in cartridge valve designed for efficient pressure relief in hydraulic systems. This pilot-operated valve is part of the DB.K product family, which falls under the pressure valves type DB..K.. for block design installation, predominantly used for system pressure limitation. The model features a maximum operating pressure of 315 bar and is capable of handling a maximum flow of up to NG6 l/min, ensuring reliable performance in demanding applications.
The valve's functionality is based on its poppet type spool that remains closed in its initial position. System pressure acts on this spool, and when it exceeds the set value, the pilot poppet opens to allow hydraulic fluid to flow and relieve excess pressure, thus maintaining system stability. The adjustment options available to set the system pressure include a rotary knob among others, offering flexibility and precision for various operational requirements.
This particular model boasts an internal pilot oil supply with an external pilot oil return mechanism. It also features FKM sealing material known for its chemical resistance and durability. The valve's robust design includes ports number Mx for seamless integration into hydraulic circuits.
Suitable hydraulic fluids for this valve are HL, HLP, HEES, and HEPG types, accommodating a range of industry standards for fluid compatibility. With its comprehensive product group ID classification within Bosch Rexroth's offerings, the DB 10 K1-4X/315YV stands out as a reliable component for effective pressure management in hydraulic systems where quality and performance are paramount.

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.
