Rexroth Type DB10 Relief Valve | DB10-1-5X/315 | DB10-1-5X/100 | Pilot Operated Pressure Relief Valve

DB10 Series Pilot Operated Pressure Relief Valves

Product Overview: The DB10 series is a high-performance, pilot-operated pressure relief valve engineered to limit the maximum system pressure in hydraulic circuits. Functioning as the “safety guard” of industrial systems, the DB10 offers pressure stability and high flow regulation capabilities far superior to direct-operated valves. Its pilot-controlled design ensures minimal override pressure even as the flow rate increases. Widely used in machine tools, hydraulic power units (HPUs), and automated production lines, it offers subplate mounting (ISO 6264 standard) for seamless integration.

Featured models include: DB10-1-5X/315, DB10-1-50B/315, and DB10-1-5X/100.

Key Technical Advantages:

• Superior Pilot-Stage Control: The pilot-operated logic maintains smooth pressure characteristics during high-pressure and high-flow shifts, effectively neutralizing hydraulic shocks.

• Wide Pressure Setting Range: Whether for high-pressure applications (315 bar) or low-to-medium circuits (100 bar), the valve allows for precise manual adjustment.

• Reliable 5X Design Series: The 5X series represents a mature industrial standard with high contamination resistance and extended mechanical service life.

• Versatile Configurations: Available with rotary knobs or internal hexagon adjustment bolts to fit various installation space requirements.
