Pneumatically air actuated butterfly valve

Pneumatically air actuated butterfly valve is combined with pneumatic actuators and concentric or eccentric butterfly valves. The pneumatic butterfly valve stem drive the valve corn rolling 90 in the body which can realize the full open or full close action.Pneumatically air actuated butterfly valve can according to the sealing performance into metal seal and soft seal with compact structure,small volume,reliable operation,good sealing,easy maintenance installation convenient and the adoptability is strong advantages.Pneumatically air actuated butterfly valve can be widely used in petroleum,chemical industry,light industry,papermaking industrial,pharmaceutical,car automatic control system on a remote concentrated or local control.
