Abstract
A control valve includes a valve body and a valve gate. The valve gate is movably located inside the inner space. The control valve has a lower flow rate limit which is greater than zero. That is, the lower flow rate limit has no necessary to be zero, thus it is acceptable to have a cylindrical valve gate but not a spherical valve gate, and a diameter of the cylindrical valve gate is be smaller than a caliber of an opening of the valve body. Therefore, the valve gate can be directly installed into the valve body via the opening, which allows the valve body to be made of a single piece so as to simplify the processes of manufacturing and assembly.
