Advantages of a Butterfly Valve 

1. Turning on/off easily and rapidly with less force. Having less fluid resistance and can be operated frequently.

2. Simple structure, small size and short face to face dimension, which suitable for large diameter valves.

3. It can be used for transmitting mud, fewer liquids are stored at apertures of pipe.

4. Long service life. Standing the test of tens of thousands of opening/closing operations.

5. Butterfly valves have excellent regulation performance.

6. Small torque. The pressure on discs at the two sides of the spindle is almost equal, causing contrary torque. Thereby, the valves can be opened with less force.

7. Sealing face is generally med of rubber or plastic. So the butterfly valves can be with good sealing under low pressure.
