Post indicators are mounted end to end with the extension spindle connecting the valve. They are mounted in places where direct access is impossible, for intance on gate valves mounted on a water ring main in an airport or a factory area with e.g. oil refineries or chemical plants.
The post indicator indicates whether the valve is in open or closed position. According to government regulations it must be easy for firemen to see whether the valve is open or closed, even at a long distance. The post indicator signs “OPEN” and “SHUT” are mounted on the target according to valve size.
