1. Opening and closing convenient, labor-saving, fluid resistance is small, you can often operate.
2. Simple structure, small size, short structure length, small size, light weight, suitable for large-caliber valves
3. The slurry can be transported at the pipe mouth to accumulate liquid at least.
4. Low pressure, can achieve good sealing.
5. Good regulation performance.
6. The effective flow area of the seat channel is large and the fluid resistance is small.
7. The opening and closing torque is small, because the hinge on both sides of the butterfly plate is basically equal to the medium, and the direction of the torque produced by the opposite, thus opening and closing more labor.
8. Sealing surface materials are generally used rubber, plastic, so low pressure sealing performance is good.
9. Easy to install.
10. Flexible operation and labor-saving, can choose manual, Electric, pneumatic, hydraulic mode.
