The pneumatic actuators for butterfly valves work with the help of a shutter, corresponding to a disk held in the guide with an upper stem equipped with an “anti-ejection” system. Each disc is made of stainless steel or cast iron or bronze-aluminum and can be operated directly by hand, although obviously you need the right skills to operate it at its best. The pneumatic actuators for butterfly valves that we make available are used in various sectors such as: pneumatic transport, waterworks, petrochemical – chemical, food industry, thermoelectric power plants, air conditioning systems. The pneumatic actuators are suitable for LUG and WAFER type butterfly and can be obtained with gaskets in NBR EPDM FKM and other materials.
