DBW Series Pilot-Operated Solenoid Relief Valves

Product Overview: The DBW series pilot-operated solenoid relief valves are critical pressure control components that integrate pressure limiting with solenoid-actuated unloading functionality. Featuring a top-mounted directional solenoid valve, this series allows for remote system unloading or pressure switching without altering the primary pressure setting. Whether using the DBW10B (Size 10) or the high-flow DBW20B (Size 20), these valves maintain excellent pressure linearity under high-pressure conditions up to 315 bar. Their compact subplate mounting design complies with ISO 6264 standards, making them the preferred choice for diverse industrial hydraulic power units.

Featured models include: DBW10B1-52/315-6EW230N9K4, DBW10B1-52/315-6EG24N9K4, and DBW20B1-52/315-6EG24N9K4.

Key Technical Advantages:

• Integrated Unloading Function: Equipped with a high-performance solenoid valve, enabling electrical remote control for system unloading to reduce energy consumption and heat generation.

• Precision Pilot Control: The pilot-operated architecture ensures small pressure overrides and smooth opening characteristics, effectively preventing hydraulic shocks.

• Heavy-Duty Reliability: Rated for pressures up to 315 bar, designed for high-intensity continuous operation in machinery like extruders, injection molders, and heavy presses.

• Low Noise Design: Optimized damping orifices and spool structures significantly reduce vibration and fluid noise during high-pressure relief cycles.
