A butterfly valve actuator is a device which enables the butterfly valve to be used.  There are different types of butterfly valve actuator.  It can be a manual handle, gear, pneumatic, electric and electro-hydraulic.  There are also actuators that can be enclosed in special housings and buried for certain underground applications.  Where is a butterfly valve actuator used?  A butterfly valve actuator is used in any area where butterfly valves are necessary.  Basically, they are used to control the flow of material through a circular pipe or tube.  Typically, the material is air, gas, steam or liquid although certain dry materials can also be handled through a butterfly valve.  Butterfly valves offer an excellent, economically priced, positive shut off valve for handling materials such as gases and liquids that are easily displaced by the valve disc as it closes.  When handling this type of material, bubble valves provide a reliable, bubble-tight , bi-directional shut off.
