Description

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
