Product Description
Electric Three Eccentric Metal Hard  seal butterfly valve, the use of three eccentric structure design, the valve plate in the open and closed range of the whole range are no friction with the valve seat, eliminating the rotary control valve valve seat opening and closing caused by the valve seat caused by wear Of the leak. Seat with multi-level structure, the use of metal and non-metallic materials, the perfect combination of sealing surface, in high temperature and low temperature conditions are good use, and now in the petrochemical industry, defense industry, aerospace, power equipment, iron and steel metallurgy, It is widely used in industries such as HVAC, bio-pharmaceuticals, surface treatment, painting equipment, filling equipment, drying equipment, shipbuilding industry, automatic control, textile printing and dyeing. It is also the first choice for construction and technology construction.
