装置。 In a rotary valve in which an input shaft projects from the upper part of an actuator connected to a valve stem and opens and closes a valve body, and the input shaft is rotated from the outside, the upper part of the actuator is sealed with liquid and prevented from rotating. cylinders each having a built-in piston are connected to each other, the input shaft is passed through the center of the piston, and a thread is formed in the penetrating part so that the cylinders are screwed together, and the cylinder is sealed against the liquid. A rotary valve characterized in that one side is connected via a conduit to an opening meter installed outside, and the valve opening degree is displayed using changes in liquid volume caused by the vertical movement of the piston. Remote opening display device.
