Electric hard seal butterfly valve is a fluid control device mainly used to regulate or cut off the flow of medium. It controls the rotation of the butterfly plate through an electric actuator to achieve opening, closing, and adjusting functions.Compact structure, small volume, light weight, easy to install and operate. It is achieved by controlling the rotation of the butterfly plate through an electric actuator (such as an angular stroke electric actuator) to open, close, and adjust the valve.
