Abstract
A manifold valve having two valves, which enables operation of one valve while disables operation of the other valve, is compact, and facilitates installation in and detachment from a pipeline, that is, a manifold valve provided with a main passageway, a branch passageway split off from the main passageway, a main passageway valve opening and closing the main passageway, and a branch valve opening and closing the branch passageway, the main passageway, the branch passageway, the main passageway valve, and the branch valve being integrally formed, wherein the main passageway valve and the branch valve are each a manual valve having a valve element, a stem connected to the valve element, and an operating lever connected to the stem, the operating lever pivoting in an axial direction of the stem to open and close the passageway, the main passageway valve and the branch valve each converting pivoting motion of the operating lever to linear motion of the valve element and pressing the valve element against and separating it from a valve seat to open and close the passageway, an interlock mechanism further provided wherein when one valve between the main passageway valve and the branch valve is in an open state and the other valve is in a closed state, the operating lever of the one valve disables pivoting motion of the operating lever of the other valve.
