Rexroth DBDS Series Direct-Operated Relief Valves

Product Overview: The Bosch Rexroth DBDS Series is an industrial-grade, direct-operated pressure relief valve specifically engineered for system overload protection and pressure regulation. With its compact architecture and rapid response time, the DBDS valve is the premier choice for safeguarding pump stations, hydraulic motors, and critical circuits against overpressure damage. The specialized 2K design denotes its specific mounting configuration and adjustment handle options, providing long-term stable pressure modulation.

Featured models and material numbers: DBDS2K2X/200 (R900203852) and DBDS2K2X/315 (R900203853).

Key Technical Advantages:

• Instant Overpressure Protection: The direct-acting, spring-loaded structure ensures the spool opens instantaneously once the pressure exceeds the setpoint, securing system integrity.

• High-Precision Pressure Setting: Features smooth adjustment screw resistance and excellent linearity, allowing for fine-tuned calibration even up to 315 Bar.

• Exceptional Sealing Performance: Precision-ground spools and seats ensure ultra-low internal leakage in the closed position, maximizing overall system volumetric efficiency.

• Versatile Pressure Grading: Covers standard industrial stages including 200 Bar and 315 Bar, catering to a wide range of light-to-heavy duty equipment.
