Understanding Electric Butterfly Control Valves: Operation, Advantages, and Applications
What Is an Electric Butterfly Control Valve?
As a premier control valve manufacturer in China, we provide high-quality valves and actuators engineered for diverse industrial applications.
An Electric Butterfly Control Valve is a flow regulation device widely used in large piping systems to control fluids, gases, or slurries. It features a circular disc mounted on a spindle that pivots at right angles to the flow. Rotating this disc opens or closes the valve, regulating flow through the pipe. The “butterfly” name reflects the disc’s resemblance to a butterfly’s wings when partially open.
In electric versions, an electric actuator drives the disc’s rotation, enabling automated, precise control based on signals from a centralized system. This eliminates the need for manual adjustments and allows continuous flow modulation with high accuracy.
How It Works
The valve consists of two main components: the butterfly valve body and the electric actuator. When fully closed, the disc blocks flow by sitting perpendicular to the pipe axis. When open, it rotates toward parallel alignment, allowing fluid passage. The electric actuator controls this rotation, typically from 0° (open) to 90° (closed), in response to control signals.
Automation allows integration with sensors or control systems that adjust flow based on temperature, pressure, or other process variables. This enables applications ranging from simple on/off control to complex modulating flow regulation.
