The Bosch Rexroth DB 10 K1-4X/200Y (R900425806) is a high-performance screw-in cartridge valve designed for efficient pressure relief in hydraulic systems. This pilot-operated valve falls under the product family classification of pressure relief valves and is specifically engineered to facilitate system pressure limitation by allowing users to set the desired system pressure via an adjustable rotary knob. The DB 10 K1-4X/200Y valve operates with a maximum operating pressure of 350 bar (5076 psi) and can handle a nominal flow up to 200 l/min (52.8 gpm), ensuring it can accommodate various hydraulic applications requiring precise pressure control.
The valve features internal pilot oil supply and external pilot oil return, which together with its poppet type spool, ensures reliable operation and consistent performance. The sealing material used in this valve is NBR, which offers good resistance to hydraulic fluids such as HL and HLP, enhancing the durability and longevity of the component in challenging environments.
The DB 10 K1-4X/200Y is part of the DB.K product family type, known for their robust block design installation that simplifies integration into hydraulic circuits. It also includes multiple adjustment options such as a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale for enhanced control based on user preference or application requirements.
In addition to its core capabilities, this Bosch Rexroth relief valve stands out for its straightforward maintenance procedures due to its cartridge design—allowing for easy replacement without extensive system downtime. With these features combined, the DB 10 K1-4X/200Y provides a reliable solution for maintaining optimal hydraulic system performance by effectively limiting system pressure according to user-defined settings.

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.
