What is an Wafer Type Butterfly Valve With Electric Actuator? Wafer Type Butterfly Valve With Electric Actuator is a type of valve designed to control the flow of liquids through a pipeline. It consists of a circular disc mounted on a shaft passing through the center of the valve body. The disc can rotate around the shaft, allowing it to open and close the flow of fluid through the valve. Electric actuation means that the valve can be opened and closed using an electric motor rather than being manually actuated. Wafer butterfly valves are designed to be mounted between flanges with a wafer-shaped disc inserted between flanges and held in place with bolts. This allows the valve to be easily installed without the need to cut the pipe or make other changes to the piping system. Where is the Wafer Type Butterfly Valve With Electric Actuator Used? Wafer Type Butterfly Valve With Electric Actuator is typically used in applications where precise control of fluid flow is required, such as in industrial processes or the operation of power plants. They are also frequently used in applications where the valve must be able to be opened and closed quickly and reliably, such as in emergency shut-off systems.
