Abstract
Apparatus for handling gaseous streams comprising modular flow block means, including a plurality of gas flow paths extending through said modular flow block means so as to provide a plurality of port members on respective surfaces of said modular flow block means, a plurality of valve passages extending into said modular flow block means so as to intercept said gas flow paths at predetermined locations throughout said modular flow block means, each of said plurality of valve passages including an entrance aperture on a respective surface of said modular flow block means, a plurality of valve flange members, each of said valve flange members being adapted to mount a high vacuum valve on said modular flow block means at one of said entrance apertures without the need to apply rotational force to said valve flange members, so as to removably, hermetically seal said high vacuum valve onto said modular flow block means, and each of said plurality of port members including port member mounting means whereby conduits can be removably, hermetically sealed to said respective plurality of port members.
