Double Eccentric Butterfly Valve

As one of the best double eccentric butterfly valve manufacturers in China, UTMOST provides types of superior double offset butterfly valve. The double eccentric butterfly valve China structure enables the spherical surface of the double offset butterfly valve plate and the sealing element surface to be quickly separated and contacted when switching, reducing the friction torque between the valve plate and the sealing element, reducing wear and improving the butterfly flange valve life. 


Double Eccentric Butterfly Valve Features

The double offset butterfly valve plate cannot be separated from the sealing surface near the upper and lower ends of the valve plate in the range of 0-10°, and it is still in a sliding friction state. At this time, the torque is large, which may easily cause scratches and bites in this area. This can cause seal leakage. From the structural analysis, the double eccentric is a unidirectional butterfly valve. This double eccentric butterfly valve from china is mainly suitable for the drainage of water plants, power plants, steel smelting, chemical engineering, water source engineering, environmental facility construction, and other systems, especially suitable for water pipelines, as regulating and intercepting equipment. Compared with the centerline butterfly valve, the double eccentric butterfly valve is more resistant to high pressure, has a longer life, and has good stability. Compared with other valves such as 2 way globe valve, the larger the caliber, the lighter the material, and the lower the cost.
