Ghibson butterfly valve manufacturing started 1984 in Bologna, Italy – but has also specialized in manufacturing check valves and damper valves.
Ghibson fits Mento perfect since they are a family-owned company who listen to their customers and identify the best solution, in terms of materials and configurations.
Their production is based on modern machining facilities and materials coming only from certified foundries and mills.
Their soft seated butterfly valves are designed to meet with most industrial applications, from powder conveyance to petrochemical requirements. Feature as a special designed shaft-disc connection, higher shaft tensile capacity, greater sealing towards the outside contamination, adjustable lower seat, optimized disc shape to reduce pressure drop, anti-blow out stem and replaceable seats to mention some of them.

Their high performance butterfly valves are specifically designed for high demanding applications where the valve performance is critical.

Available in different materials and ratings. The Fire safe version is Fire tested to API607-6th edition.
Special feature like two sets of Belleville washers for better sealing even at high temperatures, special shaped shaft-disc connection which ensures an accurate coupling while avoiding clearances (higher shaft tensile capacity), the metallic seat is composed by an Inconel ring and two graphite packings and both upper and lower shafts are guided by stainless steel + PTFE bushings to mentioned some.

Ghibson manufacture their own actuators, or sub-contract if a special brand is preferred. Mento can also do actuation adaption in our workshop or fit the valves with complete control systems based on clients requirements.
