1. It is convenient, quick, labor-saving, and has low fluid resistance. It can be operated frequently.
2. Simple structure, small size, short structure length, small size and light weight, suitable for large diameter valves.
3. The mud can be transported and the liquid is accumulated at the mouth of the pipe.
4. Under low pressure, a good seal can be achieved.
5. The adjustment performance is good.
6. The valve seat channel has a large effective flow area and a small fluid resistance when fully opened.
7. The opening and closing torque is small. Since the butterfly plates on both sides of the rotating shaft are basically equal by the medium, the torque is generated in the opposite direction, so the opening and closing is relatively labor-saving.
8. The sealing surface material is generally made of rubber and plastic, so the low-pressure sealing performance is good.
9. Easy to install.
10. Flexible and labor-saving operation, manual, electric, pneumatic and hydraulic modes are available.
