A micro-fluidic valve apparatus configured to operably mount a micro-fluidic valve assembly, having a drive assembly, directly to a communication face of a fluid distribution manifold, in a fluid-tight manner, said fluid distribution manifold defining a plurality of fluid distribution channels each having a respective communication port terminating at the manifold communication face, said apparatus comprising: a housing having a proximal portion and a distal mounting end configured for mounting contact with the communication face of said fluid distribution manifold, said housing having an interior wall defining an interior central passage extending from an opening at the housing distal mounting end to the housing proximal portion; a stator device disposed in said interior central passage, in a seated position, such that a distal stator face thereof is oriented substantially adjacent to the housing distal mounting end, said stator device further defining a plurality of stator passages terminating at respective communication ports at said distal stator face, characterised in that said distal stator face, and the housing opening into the central passage at the distal mounting end collectively define a gasket receptacle when said stator device is oriented in the seated position; and a relatively thin, single-piece elastomeric gasket member having a proximal gasket face and an opposed distal gasket face, said gasket member being configured for disposition in the gasket receptacle of the housing in abutting contact between said proximal gasket face and said distal stator face, said gasket member further defining a plurality of independent through-holes, wherein each gasket member through-hole includes, on at least one of the proximal gasket face and the distal gasket face, a moulded-in O-ring seal surface circumferentially upstanding respectfully therefrom, and surrounding each through-hole thereof, each independent through-hole strategically positioned such that when the housing is securely mounted to said fluid distribution manifold, said distal gasket face contacts the manifold communication face in a compressed condition, to form a fluid-tight seal between each respective stator communication port and a corresponding manifold communication port. a housing having a proximal portion and a distal mounting end configured for mounting contact with the communication face of said fluid distribution manifold, said housing having an interior wall defining an interior central passage extending from an opening at the housing distal mounting end to the housing proximal portion; a stator device disposed in said interior central passage, in a seated position, such that a distal stator face thereof is oriented substantially adjacent to the housing distal mounting end, said stator device further defining a plurality of stator passages terminating at respective communication ports at said distal stator face, characterised in that said distal stator face, and the housing opening into the central passage at the distal mounting end collectively define a gasket receptacle when said stator device is oriented in the seated position; and a relatively thin, single-piece elastomeric gasket member having a proximal gasket face and an opposed distal gasket face, said gasket member being configured for disposition in the gasket receptacle of the housing in abutting contact between said proximal gasket face and said distal stator face, said gasket member further defining a plurality of independent through-holes, wherein each gasket member through-hole includes, on at least one of the proximal gasket face and the distal gasket face, a moulded-in O-ring seal surface circumferentially upstanding respectfully therefrom, and surrounding each through-hole thereof, each independent through-hole strategically positioned such that when the housing is securely mounted to said fluid distribution manifold, said distal gasket face contacts the manifold communication face in a compressed condition, to form a fluid-tight seal between each respective stator communication port and a corresponding manifold communication port.
