DEVICE FOR CONVERSION OF VALVES TO SUPERVISED VALVES

摘要

A device for converting a valve to a supervised valve is disclosed. The device includes a housing in which a coupling member is movably mounted. The coupling member is engageable with the actuating member of the valve when the device is mounted on the valve. A sensor is also mounted within the housing. A movable carriage is mounted on the coupling member. The carriage moves between different positions depending upon the state of the valve as open or closed. The carriage interacts with the sensor to produce a signal indicative of the state of the valve.
