To provide a low-cost air-operated valve, an air-operated valve comprises a piston, a cylinder in which the piston is allowed to slide by operation air, and a valve section to be driven by sliding movement of the piston. The cylinder includes an outer member having a hollow portion and an inner member loaded in the hollow portion of the outer member to define a piston chamber in which the piston is allowed to slide.
