The DBW20B pilot relief valve consists of a main relief valve, pilot control stage, and integrated solenoid directional valve. When system pressure exceeds the preset 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 electrical unloading and pressure switching, improving hydraulic system automation and energy efficiency.
