Flange working features:

1. A self-control butterfly valve that can be remotely controlled, and has the characteristics of a flanged butterfly valve, and can be equipped with a wide range of butterfly valves;

2. The power supply is the driving energy of the butterfly valve. It has a wide range of power sources, a wide range of applications, saves human resources and has work efficiency;

3. Easy to operate, easy to meet various control requirements, can be realized by matching different actuators, signal feedback, flow adjustment, explosion-proof and other functions;

4. Ultra-miniaturization can be achieved, mechanical self-locking can be achieved, and different sealing rings can be changed to meet different working conditions.
    How flanges work:

Using the actuator to input a standard signal of 0-10 mA, the motor unit drives the angular torque of the gear, turbine and worm to drive the disc to rotate. When the valve is in the fully open position, the thickness of the disc is the resistance of the medium flowing through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics.

Butterfly valves have two types of seals: elastic seal and metal seal. For elastic sealing valves, the sealing ring can be embedded on the valve body or attached to the periphery of the disc. Valves with metal sealing generally have a longer life than those with elastic sealing, but it is difficult to achieve complete sealing. Metal seals can adapt to higher working temperatures, while elastic seals have the defect of being limited by temperature. If flanged butterfly valves are required for flow control, the main thing is to correctly select the size and type of the valve.
