Abstract

The object of this invention is to provide an adjustable-stroke on / off valve. The on / off valve of this invention comprises: a valve body 10; a valve stem 40, the lower end of which has a valve body 41, which opens and closes the flow path by abutting and separating from a valve seat 14; a valve cap 30, which is disposed in a manner that allows axial movement of the valve stem and is directly or indirectly connected to the valve body; a handle 61, which is fixed to the upper end of the valve stem and allows the valve stem to rotate; and an offset member 34, which offsets the valve stem. A lower recess 35 corresponding to the fully closed position and an upper recess 36 corresponding to the fully open position are formed at the upper end of the valve cap; a rotating body 48 is disposed on the upper part of the valve stem, which is engaged with the lower and upper recesses by rotating the handle.
