NEGRI FRATELLI is an Italian company set up in 1920 which specializes in ball valves.
Negri Fratelli started the manufacturing of stainless steel and carbon ball valves under the brand name “NFG” (Negri Fratelli Grignasco) in the 1960s.
Its headquarters are located in Grignasco (Novara), an area traditionally devoted to the mechanical industry and particularly to the valve manufacturing sector.
Favored by such location, Negri Fratelli has acquired considerable experience in a very diverse range of sectors like chemical and petrochemical, hydraulic, industrial plant engineering and, in particular, it has specialized in gas distribution, with models and accessories specifically designed for that sector.
