Argus was founded in 1948. The brand produces high-quality engineered ball valves for the harshest conditions, including severe service applications prone to abrasion, corrosion and erosion. Specifically, Argus valves are commonly found in critical liquid and gaseous services in chemical, petrochemical and refinery operations. They fulfill the highest demands of fugitive emissions (FE) under ISO 15848. Special and customized designs are available for high-pressure, high-temperature and challenging applications like oxygen, nitrogen and hydrogen.

Argus specializes in metal-to-metal gas tightness applications with HVOF and spray and fuse coating (Arguloy), which enables a wide range of custom solutions. The brand introduced an innovative coating technology in 2009, followed by a new laser coating and cladding technology in 2014.
