A globe-shaped valve consisting of a valve stem 8 that is screwed into the valve body 6 and reciprocates the valve body 6, a cylinder 11 is provided with a gasket 10 attached to the upper part of the valve body 6 and that is fitted with the gasket 10 so as to be able to reciprocate in a water-sealing manner. An opening 16 is provided above the valve body 6 and directly below the tip 15 of the valve stem 8 in the valve body 6. 6 and the aforementioned opening 16.
A third passage 14 is provided which communicates with the inside of the cylinder 11, and the second passage 13 is formed to be sufficiently thinner than the first passage 12 and the third passage 14, so that when the valve is closed, the valve stem tip 15 closes the opening 16. The internal pressure of the cylinder 11 is increased to reduce the valve closing force, and when the valve is opened, the tip 1 of the valve stem is
A light-acting globe valve characterized in that 5 opens an opening 16 to lower the cylinder internal pressure and reduce the valve opening force.
