Double offset flanged butterfly valve

Double offset flanged butterfly valves have well taken the advantages of the double offset butterfly valves and the flanged butterfly valves. As the flanged butterfly valves are with simple and compact structure, stable positioning light weight, the double offset flanged butterfly valves are able to occupy these characteristics. Besides, the double offset flanged butterfly valves are generally with the high flow rate, low flow resistance and satisfying sealing performance. As for the double offset design, this kind of butterfly valve outstands for its high efficiency.

Double offset flanged butterfly valve generally consists of the valve body, disc, seat and other necessary components. For example, the body can be made of the stainless steel, copper alloy, cast iron, ductile iron or aluminum alloy. And seat can better be made of the rubber under the consideration of the sealing performance. This kind of valve is applicable for the control of the media such as the water, oil, gas and other causticity media. According to the different manufacturing materials, the suitable working temperature and pressure vary.
