***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth DB 10 K3-4X/200YV (R900428540) is a high-performance screw-in cartridge valve designed to serve as a pilot-operated pressure relief valve for block design installation, primarily used for system pressure limitation. The nominal flow of the valve is directly proportional to its ability to manage maximum flows of up to l/min and gpm, withstanding a maximum operating pressure of bar/psi. It features an Mx cavity and is equipped with FKM sealing material, ensuring compatibility with hydraulic fluids such as HL, HLP, HEES, and HEPG.
This particular model comes with a lockable rotary knob with scale for precise adjustment options, allowing users to set and maintain the desired system pressure accurately. The DB.K type valve includes ports and operates with internal pilot oil supply and external pilot oil return mechanisms. Its spool is poppet type, contributing to the robustness of its design.
The DB 10 K3-4X/200YV valve ensures that any counter pressures at main port are added to the set pressure, maintaining stability in hydraulic systems. This product belongs to the product family classification of pressure relief valves and falls under the product group ID for easy reference. The versatility provided by various adjustment types such as rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale or rotary knob with scale makes this component adaptable for different operational requirements.
Overall, the Bosch Rexroth DB 10 K3-4X/200YV offers reliability in controlling system pressures within hydraulic circuits while ensuring user-friendly adjustment features and durable construction for long-term performance in demanding applications.

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.
