The difference between the appearance of the flanged butterfly valve and the wafer type butterfly valve is still very large.
The flange butterfly valve has its own name from the body passages at its two ends, relative to the wafer type butterfly valve. Valves, flange type butterfly valves have a longer construction. In addition, due to the structural advantages of the flange butterfly valve, the butterfly valve is more suitable for making large diameter valves, and the scope of application is wider. For the size of the flange butterfly valve, we take the soft-seal worm gear operated flange butterfly valve as an example.
