装置。In a manual valve that opens and closes by seating or removing the valve body from the valve seat using a valve valve, it is threaded onto the feed screw of the valve stem and serves as a fulcrum by receiving thrust to guide and seat the valve body on the valve seat. The valve yoke is provided with a strain detection means for detecting the strain caused by the thrust that occurs when the valve body is seated on the valve seat, and a display means is provided for displaying the open/closed state of the valve body based on a signal obtained from the detection means. Features a manual valve open/close display device.
