Abstract
A combined valve is constructed by integrating a manual valve operating as a safety mechanism and a pilot valve. When a handle of a knob of the manual valve is in a safety mechanism release position, a valve mechanism can be opened and closed depending on whether or not there is air supply to an operation port. When the handle is in the safety mechanism release position and the valve mechanism is even in a valve open state, the valve mechanism can be forcibly brought to a valve closed state by rotating the handle to a safety mechanism set position. Further, when the handle is in the safety mechanism set position, the valve mechanism can always be kept in the valve closed state irrespective of air supply to the operation port.
