DBDS Series Direct-Operated Pressure Relief Valves

Product Overview: The DBDS Series is an industrial-grade, direct-operated relief valve designed for pressure limitation and overload protection in hydraulic systems. Thanks to its direct-acting structure, the valve offers exceptionally fast response times and a compact footprint, effectively neutralizing instantaneous pressure spikes. The DBDS series provides a wealth of mounting options, including Type K (Screw-in/Cartridge), Type P (Subplate), and Type G (Threaded/Inline), catering to everything from compact power units to heavy-duty industrial hydraulic stations.

Featured models: DBDS6K1X/200 (R900424150), DBDS10K1X/315 (R901017079), and DBDS20G1X/150.

Key Technical Advantages:

• Ultra-Fast Dynamic Response: The direct-operated design eliminates pilot-stage lag, opening in milliseconds to provide immediate safety for pumps and actuators.

• Versatile Mounting Configurations:

  • Type K (Cartridge): Screw-in design, ideal for manifold block integration.

  • Type G (Threaded): For direct installation within hydraulic pipelines.

  • Type P (Subplate): Standardized interface for modular plate mounting.

• Broad Pressure Gradients: Supports multiple pressure adjustment ranges from 25 bar to 630 bar, ensuring high precision across various operating windows.

• Rugged Industrial Quality: Features a hardened valve body and spool, maintaining superior sealing and an extended service life even under high-frequency relief conditions.
