FMC Technologies distributes gas micro valves with a quick response, over-center snap action and a lubrication-free operation. FMC micro valves are designed to withstand corrosive elements, and multiport connections ensure contamination-free operation.

SGE offers single outlet gas valves in 50 and 100mm, and dual outlet valves in 50mm.  SGE microcontrol valves are designed for chromatography systems in elevated temperature L-models have on-off controls of single gas streams, while T-models split the stream off into another column/detector. Both systems feature a ten-turn system for completely open to completely closed layouts.
