Hot Blast Valves

hot blast valve is designed and service proven for continuous operation to stove dome temperatures. Stove change time is kept to a minimum as it takes only 10 seconds to open or close the valve. Compared to mushroom valve designs, less space is required, the pressure drop is negligible, costly piping and cable devices are eliminated; also the capital equipment cost is considerably less. The valve can also be used for backdrafting stack control-and further, is interchangeable with the stove burner valve with slight alterations.The hot blast valve disc is driven in either direction by means of levers and links. This provides a positive drive for both the opening and closing cycles. These levers and links are fitted with self-lubricating bronze bushings at the fulcrum points with grease fittings furnished for external lubrication. A central lubrication center is an optional feature.
