ANSI Standard Stainless steel CF8 CF8M Lug Type Wafer Triple Offset Butterfly Valve
Product introduction:
API butterfly valve is according to the current standard API609 design and manufacture a kind of high performance butterfly valve, using three-dimensional eccentric oblique cone valve seat seal, butterfly plate sealing adopts new type metal embedded put on the butterfly plate and valve seat, using disc rotating pressure tight seal, so the sealing surface friction small, closed with functions of closed more and more tightly, sealing performance and reliable, so open to ensure sealing completely out of contact, to ensure the sealing surface is not damaged, 815W, 830W, 360W series of butterfly valve of the main structure characteristics of wafer and flange three eccentric structure, and 815L series butterfly valve around the main structure characteristics of the valve body will lugs design into a single flange with screw hole structure.
The triple offset metal seal butterfly valve series is a long-life and energy-saving butterfly valve. Its structure is designed based on the three-dimensional eccentricity principle, and the valve seat adopts a multi-level structure compatible with hard and soft seals or an all metal sealing structure. It is a high-performance butterfly valve product that can be used at higher temperatures and pressures. This product is widely used in pipelines for metallurgy, steel, electricity, petroleum, chemical, heating, air, gas, combustible gas, municipal water supply, and drainage, as a load stop or regulating medium flow. The three eccentric butterfly valve can correspond to various structural lengths, and due to its diverse material selection, it can correspond freely in high temperature, low temperature, and various corrosive media such as acid. Especially in terms of large diameter, its advantage of zero leakage is constantly replacing other shut-off valves.

Product features:
1. Simple external structure, small volume, light weight, low cost, and wide application range
2. The structural characteristics of this butterfly valve eliminate the disadvantage of other types of butterfly valves being over opened and unable to seal, and it can be used normally at high temperatures, overcoming the defect of easy leakage due to thermal expansion when used under high temperature conditions.
3. The valve selects different sealing surface materials according to the requirements of the medium used to ensure that the sealing surface is resistant to wear, erosion, and has a long service life.
