PURPOSE: A yoke sleeve combined with dividable pin and a valve equipped therewith are provided to conveniently maintain a yoke sleeve by combining a dividable pin to the yoke sleeve for replacing or maintaining the yoke sleeve without separating a valve cover. CONSTITUTION: Around the lower part of a yoke sleeve(20), a groove(22) of a certain length is formed and two dividable pins(23) are fixed to the groove. The dividable pin is protrudingly positioned from the surface of the yoke sleeve to function as a sill at the end of the yoke sleeve. A valve stem moves upward and downward according to the manipulation of a handle and is not separated from a yoke. If a yoke sleeve is damaged while using a valve equipped with the yoke sleeve, the dividable pin damaged from the yoke sleeve is dismantled and removed. Afterward, in the state of locating the yoke sleeve within the yoke, two dividable pins to be placed in the groove of the yoke sleeve are bolted inside the yoke. Then, the dividable pin is stably fixed around the yoke sleeve for the valve stem to move upward and downward according to the manipulation of the handle without being separated from the yoke.
