Advantages of butterfly valves

1. It is convenient and quick to open and close, labor saving, low fluid resistance, and can be operated frequently;
2. Simple structure, small size, short structure length, small size, light weight, suitable for large-diameter valves;
3. Mud can be transported, and the accumulation of liquid at the pipe mouth is the least;
4. Under low pressure, good sealing can be achieved;
5. Good adjustment performance;
6. When fully open, the effective flow area of the valve seat channel is larger, and the fluid resistance is smaller;
7. The opening and closing moment is small, because the discs on both sides of the rotating shaft are basically the same under the action of the medium, and the direction of the torque is opposite, so the opening and closing is more labor-saving;
8. The sealing surface material is generally rubber or plastic, so the low-pressure sealing performance is good;
9. Easy to install;
10. The operation is flexible and labor-saving, manual, electric, pneumatic and hydraulic modes can be selected.
