Regulating butterfly valve, manufactured by Henan Shangfa Valve Co. Ltd, is an essential component for air and gas pipelines in blast furnace hot blast systems. 

LD 41 is straight plate control valve, LD 43w is oblique plate control valve. Driving mode: electric (model: LD941W?LD943W). The structure is simple, the adjustment performance is good, and the service life is long.

Used in blast furnace hot blast furnace system air, gas pipeline, used as air regulating valve, gas regulating valve, according to the need of hot blast stove to adjust air, gas flow rate, adjustment range 0 ? 90 degrees, can not only field control, but also remote centralized control

Main Technical characteristics of regulating Butterfly Valve
1. Straight plate structure, wide range of adjustment
2. The finite element analysis and design are adopted, the structural rigidity is large, the temperature resistance is high, the deformation is not deformed, the opening and closing is reliable and smooth,
3. The external bearing design is adopted, the opening and closing of the bearing is smooth under high temperature, the bearing has the self-lubricating function, the lubricating grease is not required, and the maintenance is convenient.
4. With the domestic famous brand electric device, the remote control is realized, the positioning is reliable and accurate, and the adjustment precision is high.
