          What is an Actuated Butterfly Valve?

          For the uninitiated, an air actuated butterfly valve is a type of valve that uses compressed air to control the flow of liquids or gases in a pipeline. The valve’s primary component is a disc or “butterfly” that rotates on a hinge to open or close the flow path.
          They’re named “wafer” not because they’re deliciously thin and crispy (though they are slim in design), but because they fit snugly between two pipe flanges without the need for additional fasteners. This design makes them compact and ideal for tight spaces where a robust seal is required.
