Abstract
A manual valve includes a knob, a stem, a stopper, and a male thread. The stem is extended from the knob. The stopper is extended from the stem. The male thread is extended from the stopper. The stem is smaller than the stopper in outer diameter. The stem is configured to be installed with a clip, which is a separate component from the manual valve. The stopper is configured to make contact with the clip in the axial direction and to be regulated movement in the axial direction when an outer periphery of the stem is installed with the clip and circumferentially surrounded with the clip.
