The butterfly valve can be divided into flange type butterfly valve and wafer type butterfly valve according to different connection methods. In the previous article, I introduced you to “What is a wafer butterfly valve”?Then, let's talk about what is a flanged butterfly valve,as well as the flange size of butterfly valve and flanged butterfly valve is the price?
Flange type butterfly valve size
Flange butterfly valve in the appearance of the structure and the difference between the wafer-style butterfly valve is still very large, flanged butterfly valve from its two ends of the body channel with its own name for the two flanges, relative to the wafer type butterfly valve, flange type The butterfly valve has a longer structure. In addition, due to the structural advantages of the flanged butterfly valve, the butterfly valve is more suitable for making a large-diameter valve, and the applicable range will be wider. Regarding the size of the flanged butterfly valve, we use the soft-seal worm gear operated flange butterfly valve as an example.
