An Electric Butterfly Control Valve is a flow control device widely used in large piping systems to regulate the flow of liquids, gases, or slurries. It consists of a circular disc (the “butterfly”) mounted on a spindle inside the pipeline. When the disc rotates, it opens or closes to control fluid flow.
The term “butterfly” comes from the shape of the disc resembling butterfly wings when partially open. The “electric” part refers to the electric actuator attached to the valve, which automates the rotation of the disc. This actuator receives signals from a control system, enabling precise, remote, and automated flow regulation without manual intervention.
Due to their compact design, reliability, and versatility, electric butterfly control valves are popular across industries like water treatment, HVAC, power generation, oil and gas, and chemical processing.
How Does It Work?
The valve has two main components: the butterfly valve itself and an electric actuator. The disc is mounted on a shaft inside the pipeline and rotates between fully closed (disc perpendicular to flow) and fully open (disc parallel to flow).
The electric actuator receives power and control signals to rotate the valve stem, adjusting the disc position. This movement regulates flow by varying how much the disc blocks the pipe. The actuator can perform simple on/off control or precise modulating control for variable flow rates.
Automation allows the valve to respond dynamically to system inputs like temperature or pressure sensors and can be controlled remotely, improving operational efficiency and reducing manual effort.
