MONOFLANGES Instrumentation
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.

Frequently Asked Questions
What pressure rating do Vimec instrumentation valves handle?
Bar-stock manifolds and needle valves are rated to 6,000, 10,000 and 15,000 psi as standard.
What is a monoflange and when is it used?
A monoflange unites primary isolation, secondary isolation and vent/calibration functions into a single flanged body, eliminating threaded connections and the contamination risk of thread sealants — widely used in upstream offshore/onshore and downstream refining instrumentation hook-ups.
Can needle valves be supplied with compression fittings?
Yes — Vimec needle valves are available with twin-ferrule compression ends as an alternative to threaded connections, reducing leak paths.
What materials are available for instrumentation valves?
Carbon steel, stainless steel, low-temperature steel, alloy and duplex steel, machined from bar-stock.
Where are Vimec valves manufactured?
Entirely designed, engineered and manufactured at our facility in Bolgare, Bergamo, Italy.
What quality certifications does Vimec hold?
ISO 9001:2015, PED Directive 2014/68/EU, API 6D, Fire Safe, Fugitive Emission ISO 15848-1, ATEX and ACHILLES.
