The characteristics and application prospects of API butterfly valve

API butterfly valve is a kind of high performance butterfly valve and designed with API 609 standard, it adopts three-dimensional eccentric oblique cone valve seat seal, butterfly disc 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, so the closer the butterfly valve level is, the tighter it becomes, and sealing performance reliable, open to ensure sealing completely out of contact, to ensure the sealing surface is not damaged, and its connection ways including wafer, flange and lug types, its features as following,

1. Lightweight and easy to operate, easy to install: The design of the three eccentric butterfly valve makes it a lightweight and easy to operate valve, which simplifies the installation process, reduces the required pipeline support, and also makes it easy to replace the valve seat ring. ‌
2. Low torque and bidirectional sealing function: Due to its low torque characteristics, the three eccentric butterfly valve does not require the use of larger valves, thereby significantly saving costs. In addition, both ends achieve zero leakage and have bidirectional sealing function, which is not limited by the flow direction and spatial position of the medium, and can be installed in any direction. ‌
3. Excellent cutting performance and durability: The design of the three eccentric butterfly valve has excellent cutting performance and durability, with small size, light weight, good sealing performance and corrosion resistance, and long service life. ‌

The application prospects of triple eccentric butterfly valves are very broad, mainly used in industrial pipelines such as metallurgy, power, petrochemicals, water supply and drainage, and municipal construction, as a means of regulating flow and cutting off fluids. In addition, due to its excellent performance, the three eccentric butterfly valve is also suitable for fields such as heat, energy, and light industry, with advantages such as small size, light weight, economic practicality, and easy maintenance. ‌

In summary, the three eccentric butterfly valve occupies an important position in the industrial field due to its unique design and excellent performance, and has a wide range of application prospects.
