FD-H Series Bi-eccentric High-Performance Butterfly Valve

Overview and application

Bi-eccentric high-performance butterfly valve is an energy-saving valve with a long service life that applies eccentrically designed structure. It is widely applied on pipes with corrosive media such as air, coal gas, combustible gas and water in industries like metallurgical industry, electric power industry, petroleum industry and chemical industry, like working conditions involving sea water desalination, air separation, high and intermediate pressure condensate and coal gas.
