Advantages Of Butterfly Valve

- Oct 02, 2018-

 

Butterfly valves have these advantages:

 

1. opening and closing is convenient, fast, labor-saving, low fluid resistance, and can be operated regularly.

2. Simple structure, small size, short structure length, small volume, light weight, suitable for large-diameter valves

3. mud can be transported and liquid stored at the pipe mouth minimum.

4. good seal can be achieved under low pressure.

5. good regulation performance.

6. when the valve is opened, the effective flow area of the valve seat is larger, and the fluid resistance is smaller.

7. Opening and closing torque is small, because the two sides of the rotating shaft butterfly plate by the medium action is basically equal, and the direction of torque is opposite, so opening and closing is called labor-saving.

8. sealing surface materials generally use rubber, plastic, so low pressure sealing performance is good.

9. easy installation

10. the operation is flexible and labor-saving. Manual, electric, pneumatic and hydraulic methods can be selected.
