Automatic valves are operated by a special switch that is installed for them. In this way,if its special switch is inside the valve,the water will be flow in the valve and pipes,and if the switch comes out of its place,the water flow will be cut off. The hose or pipe is usually connected to one end of the switch and the other end is inserted into an automatic valve to allow water to flow through the pipes.
