FMC Technologies offers micro valves for pressure switch, level control, air switch, pilot operation, limit switch, diverting valve, and machine stop applications. FMC's micro valves allow no leakage, guarantee sure response, allow no sliding seals/packing/tight-fitting moving parts, require no lubrication, and are suitable for vacuum service.

SGE Inc. designs microcontrol valves specifically for chromatography applications and may be used at elevated temperatures from high vacuum to medium pressure. The valves are vacuum rated to a leak rate of 1 x 10-5 cc/sec of Helium except for BMCV and SMOV, which are not tested for this application. Valves have a pressure rating of 700psi  and a flow rate ranging from 0 to 2000mL/min. Stem lengths range from 50-100mm. Valves provide a minimal exposure to stainless steel, a fully swept flow path, easy installation, minimal dead volume, etc.

Valco Instruments Co Inc offers micro valves for liquid or gas handling applications. Valves have a bore size of 0.060" and can handle up to 200 psi. Valves come in a compact 1" design and the internal valve parts are made of PEEK and PTFE. "T", 90°, and 180° flowpath configurations are available.
