Abstract
A manually operated mode-selecting valve device allowing pressurized air to be transmitted to a plurality of working agents so as to actuate them simultaneously with the movement of a single valve medium upon operating a corresponding single actuator is disclosed. The operational force required is reduced to such a point as that merely needed to move a single number of the valve medium. The valve medium serves as an air-passage way in cooperation with an air-passage forming medium, thereby rendering reducing the number of part components together with structural simplification.
