Abstract: A shutoff valve assembly for a fluid supply system includes a shutoff valve, with a valve member movable therein to shutoff fluid flow through a fluid conduit. The shutoff valve assembly includes a sensor target assembly with a sensor target located outside of the valve housing, and a rotator structured to transmit a rotation of the valve member within the valve housing to the sensor target. A proximity sensor is located outside of the valve housing and structured to produce a valve closing signal based on rotation of the sensor target that is indicative of initiating closing the shutoff valve. The design is adapted for relatively high temperature and high vibration environments.

Abstract: A fluid supply system for a machine such as an internal combustion engine includes a shutoff valve having an electrical actuator that includes a solenoid subassembly, and a stabilizer for the electrical valve actuator. The stabilizer includes a fitting structured to couple the shutoff valve to adjacent hardware in the fluid supply system, and a strongarm extending between the fitting and the solenoid assembly and clamped to the solenoid subassembly. A vibration-damping reinforced grommet may be clamped between the solenoid subassembly and the clamp.

Abstract: An air shutoff valve for use on an internal combustion engine includes a gate that is moveable between armed and triggered positions by springs when a release pin is retracted and allows a spring loaded retention pin to retract and release the gate, which is also spring loaded, to drop. The release pin is operated by an actuator.
