What is advantage compared to normal butterfly valve

Double offset butterfly valve have more resistant to high pressure, has a longer life and good stability. Compared with other valves. When you would like to achieve bigger donimal diameter, flange type double offset butterfly is better choice. Because the larger the diameter can achieve lighter the material, so you could get the lower the cost.
