ABSTRACT Valve apparatus for use in an apparatus for the sequential perform- ance of chemical processes to control the flow of fluids therein, comprising valve block means having a plurality of substantially flat valving sites on a surface thereof said valve block means defining a primary passage continuous between two ends thereof and communicating through primary openings with each of said valving sites and a plurality of secondary passages each communicating through a secondary opening with one of said valving sites; and a plurality of resilient, substantially impermeable diaphragms covering said respective valving sites, each of sail diaphragms being actuable between a first sealing condition in which it is forced against one of said valving sites to close off the primary and secondary openings communicating with said site and a second condition in which it is drawn away from said site to provide a fluid flow path between said primary and secondary openings over the exterior of said valve block means; whereby fluid flow between said primary passage and said secondary passages can be selectively controlled. This valve finds particular use in apparatus for the sequential performance of chemical processes.
