Product Description

Electric ventilation butterfly valve (damper) with customized valve bracket or swinging arm




DCL electric ventilation butterfly valves are widely used to shut off, control, divert or reduce the flow of corrosive and chemically-polluted exhaust air, flue gases and process gases. Such as following industries.

• Domestic and special waste incinerators

• Thermal power plants (e.g. gas turbine plants)

• Smelting works, production of precious and special metals, e.g. steel, copper, gold, silver, platinum, titanium, palladium

• Cement works and mineral oil refineries

• The process industry (chemicals, pharmaceuticals, foodstuffs) and the semi-conductor industry
