As his son joined the company, the valve business was developed, especially: One-Piece Ball Valves, High Pressure Ball Valves,Flanged Ball Valves,Wafer Ball Valves,Split Body Ball Valves, 3-Way Ball Valves, Globe Valves and Pin Valves.

In addition, custom valves completely designed and built in-house at the production site in Nerviano in the province of Milan.
