Product Description

Rexroth Type DBD & DBDS Series Direct-Acting Relief Valves

Product Overview: The Rexroth DBDS Series is an industrial-grade direct-acting relief valve designed specifically for limiting peak pressures within hydraulic systems. Renowned for its rugged construction and instantaneous response, this series is the premier choice for safety protection across diverse machinery. Whether functioning as a system safety valve to prevent overpressure or as a back-pressure valve for regulation, the DBDS series provides precise and stable control across a wide range of 50 Bar to 400 Bar.

This selection features essential configurations: the subplate-mounted DBDS6G1X and the high-capacity, high-pressure DBDS30K1X/315 (R900423722).

Key Technical Advantages:

  • Instantaneous Response: System pressure acts directly on the valve poppet without a pilot stage, allowing the valve to react immediately to pressure spikes and protect precision components.

  • Versatile Adjustment Options: Available with hand knobs, hexagon socket screws, or lockable adjustments (DBDH/DBDS series) to meet specific safety and maintenance requirements.

  • Superior Stability & Vibration Control: The optimized internal flow path ensures minimal vibration and quiet operation even during full-rated relief flows.

  • Global Mounting Standard: Available in threaded connections (DBD), subplate mounting (DBDS..G), or cartridge structures to fit any manifold design.
