DBW10B-1-50B/3156CG24N9Z5L Hydraulic Valve Pilot Operated Electromagnetic Relief Valve

The DBW10B-1-50B/3156CG24N9Z5L is a pilot-operated, solenoid-controlled relief valve designed for precise pressure regulation and system protection in hydraulic circuits.

This valve combines a main pilot-operated relief valve with a 2-way, normally closed solenoid valve. It allows for remote, electrical control over the system's pressure setting. When the solenoid (rated for 24V DC) is de-energized, the valve acts as a standard relief valve, bleeding off excess pressure to protect the system. When the solenoid is energized, it vents the pilot stage, effectively unloading the pump to tank at a very low pressure, which saves energy and reduces heat generation.
