ルブ。[Claims for Utility Model Registration] A valve rod is housed in a flow pipe in a cylinder, a piston is slidably attached to the flow pipe, and a cylindrical alternating polarity multilayer magnet is attached to the valve rod. and small-diameter annular multi-layer magnets with alternating polarity are provided opposite the pistons, and the valve rod is repeatedly moved within the flow channel cylinder by repeated sliding of the pistons by external air pressure, thereby controlling the flow. In a magnetically actuated automatic valve that opens and closes a fluid outlet on the tip side of a road tube, a valve operation detection chamber is provided around the outside of the cylinder, isolated from the inside of the cylinder, and a large-diameter annular magnet is placed inside the detection chamber. 1. An automatic valve comprising: an annular multilayer magnet that is slidably housed in opposition to the magnet; and an optical fiber is attached to face the inside of the detection chamber in order to detect repeated sliding of the magnet.
