Abstract
A disposable suction valve is provided. In some embodiments, the disposable suction valve may include a stem providing an air passage through the stem, a spring, a spring stanchion cup, and a boot. A method for manufacturing a disposable suction valve may include several steps. A stem and spring stanchion cup are molded, and a bottom end of the stem is placed through the center of a spring. The bottom end of the stem is placed through a stem opening in the spring stanchion cup, and the tabs or the spring stanchion cup are placed into recessed apertures of the stem. The boot may be over-molded on the spring stanchion cup or molded and placed onto the spring stanchion cup.
