1. Easy and quick opening and closing, labor-saving, small fluid resistance, can be often operated.
2. Simple structure, small external size, short structure length, small volume, light weight, suitable for large diameter valves.
3. When the valve seat channel is fully open, the effective flow area is large and the fluid resistance is small.
4, the opening and closing moment is small, because the shaft butterfly plate by the medium action is basically equal, and the direction of the torque is opposite, so the opening and closing is less effort.
5, sealing surface materials are generally rubber, plastic, so the low-pressure sealing performance is good.
6. Flexible and labor-saving operation, manual, electric, pneumatic and hydraulic modes can be selected.
