Product Features

1. Simple structure, small external size, short structure length, small volume, light weight, suitable for large diameter valves.
2. When fully open, the effective flow area of the seat channel is large and the fluid resistance is small.
3. Convenient opening and closing, fast, good adjustment performance.
4. The opening and closing moment is small, because the butterfly plate on both sides of the rotating shaft is basically equal to the action of the medium, and the direction of the torque is opposite, so the opening and closing is less effort.
5. Sealing surface materials are generally rubber and plastic, so the low-pressure sealing performance is good.
