In 1969, in the center of Trescore Balneario (Bergamo), Mr. Angelo Facchinetti brought his "mechanical workshop" to life. In the late 90s, the company was renamed GEMELS and manufactured the first GE2 valve model. In 2010, it made its first investment in the oil and gas market, and two years later obtained API 6D certification, producing valves up to 42 inches. In 2015, GEMELS became increasingly aware of the importance of health and safety issues, obtained ISO 18001 and OHSAS 14001 certifications, and launched the first GE automatic valve assembly machine. In 2018, GEMELS expanded its product range by introducing quick couplings. In 2020, the company was renamed GEMELS s.r.l. In recent years, GEMELS has invested increasingly in the electrical sector, established a dedicated department, introduced hydraulic and electric rotary distributors for earthmoving and lifting into its product line, expanded by acquiring new facilities, and obtained DNV certification for the marine sector.
