The Bosch Rexroth DB 6 K1-4X/315Y (R900428602) is a high-performance screw-in cartridge valve designed for efficient system pressure limitation in hydraulic applications. This pilot-operated pressure relief valve belongs to the DB.K product family, known for its reliability and precision in controlling system pressure. With a maximum operating pressure of 315 bar (4569 psi) and a nominal flow, it is capable of handling substantial hydraulic demands.
The valve features an internal pilot oil supply and an external pilot oil return, ensuring stable operation and consistent performance. The pilot poppet type design, along with the poppet spool, ensures that the valve remains closed until the system pressure surpasses the set value. Once this occurs, the pilot poppet opens allowing fluid to flow through and reduce the pressure, thus safeguarding hydraulic systems from excessive pressure buildup.
Adjustment options for this model include a rotary knob which allows users to set and monitor the system pressure easily. It also comes with other optional adjustment types such as a sleeve with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale for versatile application needs.
The DB 6 K1-4X/315Y valve is engineered to fit Mx cavities and utilizes NBR sealing material to maintain integrity under various conditions. It is compatible with hydraulic fluids HL and HLP, further ensuring its adaptability across different systems. The component series X indicates its place within Bosch Rexroth's line of innovative solutions designed for block design installation.
In summary, this product is an essential component for those requiring precise control over their hydraulic system pressures. Its robust design ensures long-term durability while offering diverse adjustment capabilities to meet specific application requirements.

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.
