Abstract
A flow amount adjusting valve includes a handle that enables an opening/closing amount of a valve plug to be adjusted. A piston connected to the valve plug is screw-engaged with a first axial portion of the handle. Additionally, along with displacement of the valve plug in the axial direction via the piston under a rotating action of the handle, an indicator element is accommodated in an interior portion of the handle. A first indicator undergoes screw-engagement with respect to the handle, and the indicator element is displaced together with displacement of the valve plug, such that displacement of the valve plug can be confirmed visually from outside the flow amount adjusting valve.
