Solenoid Valve

Solenoid valves are control units , when electrically energized or de-energized, either shut off or allow fluid flow. The actuator takes the form of an electromagnet. When energized, a magnetic field builds up which pulls a plunger or pivoted armature against the action of a spring.

In the generator, the solenoid is usually controlled by the generator control panel. When you press the start button or turn a key, power is sent to the solenoid to allow it to open, before the engine is cranked. If the solenoid is not open, the engine won’t start, because it will not have any fuel supply.
