Design Features:
1. Novel design structure, small overall size and light weight.
2. Usually the torque is small, the opening and closing is quick, and the operation is light and labor-saving.
3. The butterfly plate and the sealing ring are tightly combined, which can achieve zero leakage.
4. Flange butterfly valve connection requires shorter bolts than wafer butterfly valve, which is more reliable in the application of large-diameter pipelines. Generally, flange butterfly valve or U-shaped butterfly valve is recommended for large-diameter working conditions.
