was founded in 1969 as a Company specialized in the DESIGNING and MANUFACTURING of ball valves from 1/4" up to 24".
It became a worldwide leader in industrial & hydraulic field, GEMELS since 2010 started to focalize and to invest more and more also in OIL&GAS field. In the middle of North Italy, GEMELS is located in Trescore Balneario, Bergamo, less than 50 km from Milan, with an area of more than 10.000 mq.

The production area, where GEMELS produce more than 50.000 ball valves per month, consists of more than 40 machines including automatic numerical controlled machines and semi-automatic ones, among which CNC, lathes, transfers, boring machines, machining centers etc. These technologies and the high qualified personnel help GEMELS achieve the quality standards and excellence, obtaining the required technical characteristics and being trustworthy in the field.
After the internal assembly, all valves are 100% tested using specific test benches. Moreover, in our Internal Laboratory GEMELS qualified personnel test the life of the valves, simulating with special machineries (burst test, impulse test, saltspray test, climatic chamber...) critical applications and conditions to constantly ensure the highest quality.
