Vimec Valves Monoflanges are used in upstream offshore/onshore gas and oil production and initial processing installation. Vimec Valves Monoflanges are produced with the aim of uniting primary, secondary, and vent valves in a single body, replacing the connection to the plant by flanged threading. They are available in 4mm, 10mm bore diameter typically used in gas gauge pressure instrument applications to minimize the size and the weight of the pipeline valve assemblies used for primary and / or secondary isolation, vent and calibration. This is the purpose of eliminating any possible contamination of the fluid with thread sealants. The monoflanges can therefore be fixed onto any desired pipe, resulting in faster installation and better operating efficiency.

It is also used in downstream oil and gas refining and petrochemical production.
