Positioning of the valve shaft with respect to the valve body, centering of the screw holes of the valve shaft and the throttle valve, centering of the throttle valve by aligning the throttle valve with the bore of the valve body, and positioning of the valve shaft and the throttle valve Each step, such as screwing, can be performed automatically, and the burden on the operator is greatly reduced, and productivity is improved. In addition, by opening and closing the throttle valve with the valve shaft drive unit,
Since the throttle valve is reliably aligned with the bore and centered, the variation in the amount of fluid leakage when the throttle valve is fully closed after assembly is small.
