Product Description

Product About

Electric Butterfly Valve

Electric butterfly valve is an automated flow control device that uses an electric actuator to rotate a disc (vane) inside the pipe, allowing precise regulation or on/off control of fluids.

The products are widely applied in the temperature, pressure and flow regulation and shut-off of various industrial media.

It is widely applied in systems such as petroleum, chemical engineering, food, medicine, light textile, papermaking, hydropower, shipping, urban water supply and drainage, smelting and energy, and is used as a regulating and shut-off device on pipelines and containers for non-corrosive gases, liquids, semi-fluids and solid powders.
