Rexroth Type DBDS Valve | DBDS6K DBDS10K DBDS30K | R900424288 Relief Valve

Rexroth Type DBDS Series Direct-Operated Pressure Relief Valves

Product Overview: The Rexroth DBDS Series is a premier industrial-grade, direct-operated pressure relief valve designed specifically to limit peak pressures within hydraulic systems. Renowned for its exceptionally rugged construction and instantaneous response times, the DBDS series is the first choice for safety protection across a wide range of hydraulic machinery. Whether functioning as a system safety valve to prevent overpressure or as a control valve to maintain constant pressure, it provides precise regulation even in high-pressure environments ranging from 200 Bar to 400 Bar.

This selection features essential configurations: the compact DBDS6K, the standard DBDS10K, and the high-capacity DBDS30K (R900424288).

Key Technical Advantages:

• Instantaneous Response: System pressure acts directly on the valve poppet without a pilot stage, reacting immediately to pressure spikes to protect pumps and actuators.

• Ultra-High Pressure Endurance: Engineered for heavy-duty applications, with rated pressures up to 315 Bar – 400 Bar, meeting the demands of high-pressure hydraulic power units.

• Secure Adjustment Mechanism: Features the “K” type adjustment (hexagon socket screw with a protective cap), preventing unauthorized tampering and ensuring system parameter safety.

• Optimized Fluid Dynamics: The internal poppet is designed for damping, ensuring stable operation without high-frequency vibration or excessive noise even during full-rated relief flows.
