To provide a manifold valve which has two valves, in which one valve is so held that it cannot be opened and closed when the other valve cannot be opened and closed, and which is formed compact so that it can be easily installed in and removed from a pipe line.
In this manifold valve, a main flow path and a branch flow path are formed integrally with each other, and a main flow path valve and a branch valve are formed integrally with each other. The main flow path valve and the branch valve are manually operated valves for opening and closing each flow path by rotating each handle. One of the main flow path valve and the branch valve comprises an interlock mechanism which opens and closes a flow passage by separating and pressing the valve element from and against the valve seat through a converting means for converting the rotating motion of the handle to the linear motion of the valve element, and when one of the main flow path valve and the branch valve is closed with the other opened, disables the rotation of the handle of one valve by the other valve.
