Principle of Wafer Concentric Butterfly Valve with Post Indicator

The wafer concentric butterfly valve with position indicator is the connection between the butterfly valve and the position indicator. The position indicator is added with the electric switch box on the basis of the manual device of the valve. There is a micro switch in both open and close directions. When the valve is "closed" or "open" in place, an electrical signal can be provided. The electrical switch box is fully sealed, and the joint part of the shell is provided with a sealing ring, so it can be used outdoors.
