The shut-off solenoid valve (also known as the fuel cut-off solenoid valve) is an electro-mechanical integrated control component of the diesel engine fuel system. Its core function is to open the fuel passage when powered and close the fuel passage when power is off, enabling fuel supply during start-up, fuel cut-off during engine shutdown, and emergency stop protection.
