Perkins U85206452 Fuel Shutoff Solenoid

The Perkins U85206452 is a 12V DC fuel shutoff solenoid (stop solenoid) designed for diesel engine fuel injection pump control. It operates as an energized-to-run device: when powered, the solenoid opens the fuel supply circuit to allow engine start and run; when de-energized, it cuts off fuel flow to stop the engine. The unit features a two-pin electrical connector and a threaded mounting body for direct installation on Perkins 400 series injection pumps. Constructed with a steel housing and copper winding, the solenoid is rated for continuous duty in heavy-duty industrial environments. It serves as a direct OEM replacement for Perkins part numbers U85206452, 185206452, 185206451, 185206450, 185206420, 185206192, 185206084, U85206451, U85206450, and U85206520.
