What is an electric butterfly valve

An electric butterfly valve is a type of valve that is controlled by an electric actuator. It consists of a disc or plate that rotates within a pipe or duct to regulate the flow of fluids, such as liquids or gases. The disc is mounted on a shaft, and when the actuator receives an electrical signal, it rotates the disc to open or close the valve.

The disc in a butterfly valve is typically in the shape of a butterfly, which is where the valve gets its name. When the valve is fully open, the disc is positioned parallel to the flow direction, allowing for maximum flow. Conversely, when the valve is closed, the disc is turned perpendicular to the flow direction, blocking the flow entirely.

The electric actuator provides precise control over the position of the disc, allowing for accurate flow modulation. It eliminates the need for manual operation, as the valve can be remotely controlled or integrated into an automated system. This makes electric butterfly valves suitable for applications requiring frequent adjustments or remote operation, such as industrial processes, HVAC systems, water treatment plants, and power generation facilities.

Electric butterfly valves offer advantages such as quick response times, easy installation, and compact design. They are commonly used in situations where reliable and efficient flow control is essential, and where automation or remote control is desired.
