Abstract
A pneumatically-actuated valve is provided in which a spring member that applies an axial force to a shaft connected to a valve body, in an axial direction of the shaft, and a valve-actuating pressure chamber that actuates the valve body by applying a force resisting the axial force to the shaft are provided inside a valve casing. The pneumatically-actuated valve includes an axial-force adjusting device that adjusts the magnitude of energy stored in the spring member, via a surface-pressure adjusting screw provided to be inserted through the valve casing, from the outside of the valve casing.
