Abstract:
Stem-actuated two-way valve for precise, intermittent and repeatable delivery of fluid and/or gaseous substances from high pressure sources. A dual purpose o-ring functions as a valve seat and separates high pressure segments from low pressure segments. The novel valve stem system allows precise delivery of desired liquids and/or gases regardless of valve stem travel within a defined travel length.
