Butterfly Valve

Application and Characteristics The butterfly valve is suitable for opening and closing or adjusting medium on high temperature, high pressure, fire prevention and heat preservation pipes. Its main features are as follows: 1. Compact structure, small volume, light weight, flexible operation, easy to use; 2. Adopt three-dimensional eccentric elastic or multi-level hard sealing structure, its sealing performance is reliable to achieve zero leakage; 3. The valve has no flange,

Eccentric butterfly valve, is widely used in the medium temperature ≤425℃ metallurgy, electric power, petrochemical industry, as well as water supply and drainage and municipal construction and other industrial pipelines, used for regulating flow and load cut-off body. Material: cast iron, cast steel, stainless steel. The application range of three eccentric disc valve can withstand pressure up to 2500 pounds, temperature as low as -196 ℃, up to 700 ℃, sealing up to 0 leakage

D343H Flange type Three eccentric Multilayer Hard Seal Butterfly Valve It adopts precise J-shaped elastic sealing ring and triple eccentric multi-layer metal hard sealing structure, and is widely used in industrial pipelines such as metallurgy, electric power, petrochemical industry, water supply and drainage, municipal construction, etc. with medium temperature ≤425℃, for regulating flow and cutting off fluid. The valve adopts triple eccentric structure, the valve seat and
