Below is a list of Electric Butterfly Valve manufacturers from Riviera Beach, Florida. Electric butterfly valves are mechanisms that control the flow of a fluid through a piping system by using a round disc and an electric actuator. Butterfly valves are able to completely shutoff a pipe by using a round disc that rotates and forms a tight seal with a gasket. Typically a lever or wheel is used to rotate the disc to open and close the valve and allow or stop the current of gases, liquids and slurries.
