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.
