The electric worm gear carbon steel lined PTFE flange butterfly valve is driven by an electric actuator. Normally, AC380/AC220V voltage is selected for driving, controlling the forward and reverse rotation of the motor, controlling the valve switch, or adjusting it with a 4-20mA analog signal; The electric actuator is connected to a two-stage worm gear device, also known as an electric valve gearbox, which opens and closes the fluorine lined flange butterfly valve through gear transmission. Carbon steel WCB is used as the valve body material, lined with PFA, FEP, PTFE to isolate the corrosion of the pipeline medium.
