1. Product Overview
TheDB3U10is a multi-stage pilot-operated solenoid relief valve composed of a pilot valve and a main valve. It utilizes electromagnetic force to control the operation of the pilot valve, which in turn regulates the opening and closing of the main valve, achieving stable system pressure control. This valve is suitable for high-pressure, large-flow hydraulic systems and is widely used in industrial equipment, construction machinery, and other fields.
