cummins fuel shut off solenoid

A fuel shutoff solenoid is an electromagnetically-operated valve used to remotely cut the fuel supply to an engine. The solenoid typically consists of a valve body with an integral solenoid assembly connected to the valve stem. When the solenoid is energized, the motion of its plunger retracts the spring-loaded valve poppet from its seat, allowing fuel to pass through the valve. When the solenoid is deactivated, the valve spring pulls the poppet back onto its seat effectively cutting the flow of fuel. The shutoff solenoid may be manually activated or be part of an automated engine management system.
