Working principle of electric flange butterfly valve:
The electric flange butterfly valve uses an electric actuator to input a standard signal of 0-10 mA, and the motor unit drives the gear turbine worm and the angular torque drives the disc to rotate. When the valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body. Therefore, the pressure drop generated by the valve is very small, so it has good flow control characteristics. Electric flange butterfly valve has two sealing types: elastic seal and metal seal. For elastic sealing valves, the sealing ring can be embedded in the valve body or attached to the periphery of the butterfly plate. Valves with metal seals generally have a longer service life than valves with elastic seals, but it is difficult to achieve complete sealing. Metal seals can adapt to higher operating temperatures, while elastic seals have the disadvantage of being limited by temperature. If the electric flange butterfly valve is required to be used as flow control, the main thing is to correctly select the size and type of the valve.
