Abstract: A modular component connector substrate assembly for mounting thereon of at least one fluid control component, the assembly including at least two substrate blocks or one substrate block and an end block, all in fluid communication with each other via internal passages, with a separate fluid pressure connector fluidically interconnecting and fixedly spacing adjacent ones the substrate blocks and/or end blocks with adjacent substrate blocks, wherein the conduits connected by the pressure connector all being located in a common internal plane and thus being capable of extending in any of the compass directions (N,S,E,W) within this common plane. The bottom surfaces of the substrate and end plates abut mounting plates configured to the existing ANSI/ISA SP76 specification.
