The GD-DBW20B-1-50B/3156CG24N9Z5L Type Explosion Isolation Pilot Relief Valve / Solenoid Pilot Relief Valve is a high-performance pilot-operated hydraulic pressure control valve designed for accurate pressure regulation, overload protection, and remote unloading control in hazardous and explosion-sensitive environments. The valve combines a pilot-operated relief valve with an explosion-proof solenoid directional valve, ensuring stable pressure control, fast response, and reliable operation in heavy-duty industrial hydraulic systems.

The GD-DBW20B pilot-operated relief valve consists of a main relief valve, pilot control stage, and explosion-proof solenoid directional valve. When system pressure exceeds the preset pressure value, the pilot valve opens and releases control pressure from the main spool chamber, causing the main valve to open and redirect excess hydraulic oil back to the tank. The integrated solenoid valve enables remote unloading and electrical pressure switching, improving hydraulic system automation, safety, and energy efficiency.
