Simple introduction
D641W pneumatic ventilation butterfly valve is suitable for the occasions when thousands of pieces are cut off. The connection between valve and actuator adopts branch connection mode. The expansion gap between pneumatic ventilation butterfly valve butterfly plate and valve body is large, which can effectively prevent the stuck phenomenon caused by thermal expansion and cold contraction.
The ventilation butterfly valve USES the midline butterfly plate and the short structure steel plate welding new structure form design manufacture, USES the high quality wear-resisting material to weld, the structure is compact, the weight is light, easily installs, the flow resistance is small, the circulation flux is big, avoids the high temperature expansion influence, the operation is light.No connecting rod, bolt, reliable work, long service life, especially suitable for thousands of low pressure difference, large diameter, large flow occasions, it is used with various actuator combination, combination into different performance of the valve, can be multi-station installation, not affected by the flow of media.The ventilation butterfly valve is a kind of non-airtight butterfly valve, widely applies to the ventilation dust removal system, to the dust gas, the gas pipeline, the ventilation purification device, the flue gas pipeline, the medium temperature≤300℃nominal pressure is -0.1pma on the pipeline, for connecting, opening and closing or adjusting the medium quality.
