Electric ventilation butterfly valve


Simple introduction

D941W electric ventilation butterfly valve is suitable for cutting off the ventilation of thousands of pairs. The connection between the valve and the actuator is in the form of branch connection. The electric actuator does not need to be equipped with servo amplifier.

The ventilation butterfly valve USES the mid-line butterfly plate and the short structure copper 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 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 direction of medium. Ventilation butterfly valve is an unsealed butterfly valve, widely applicable to thousands of ventilation dust removal system, dust containing gas, gas pipeline, ventilation purification device, flue gas pipeline, medium temperature≤300℃nominal pressure is -0.1mpa on the pipeline, used to connect, open and close or adjust the medium quality.
