A filter-purifier that removes sub-micron particles as well as trace amounts of moisture, oxygen, and other chemical impurities from a gas stream. The filter-purifier has a pair of end caps, a baffle stack, a purifying medium bed to contain a purifying medium, a pair of face-seal style fittings, a pre-filter cup, a purifying medium retaining screen, a final filter, a pair of spring stacks, a pair of collars to retain the spring stacks, and a cylindrical housing welded between the end caps.

Gas filter-purifier

A first and second conduit are connected together by a screw thread attachment. A gasket hermetically seals the first and second conduit together. The first conduit has a seal member which is shaped to engage a sealing surface of the first conduit. Spring washers force the seal member against the sealing surface. The seal member has an extension which engages the gasket such that when the conduits are screwed togther, the seal member is lifted off of the sealing surface.

Face seal shut-off valve

A digital valve unit comprised of a plurality of valve orifice sections which have orifice sizes in a binary relationship. The orifice sections are detachable from the valve unit such that the unit may be modified to have different size orifices in different combinations. The unit also comprises a plurality of stackable air powered actuators. The valve actuators may each comprise a single or multiple stage, depending on the application required.
