Air Exhaust Damper Butterfly Valve

Air Exhaust Damper Butterfly Valve

The Air Exhaust Damper Butterfly Valve is generally suitable for industrial, metallurgical, environmental protection, chemical, building materials, power station, glass and other industries in the dust containing cold air or hot air gas pipeline in the ventilation and environmental protection engineering, as a gas medium to adjust the flow or cut off the pipeline control device. The Air Exhaust Damper Butterfly Valve should be installed horizontally in the pipeline.

There is no connecting rod, bolt and other components in the part, so there will be no component problems in the process of use, so the failure rate is very low.

Because there is a large gap between the butterfly plate and the valve body of the ventilation butterfly valve, there is enough expansion space, so in the process of use, it can effectively prevent the thermal expansion and cold contraction caused by the temperature change, and the butterfly plate will not be stuck

1. Manufacture is according to JB/T8692, and the face to face dimension is according to GB12221.

2. After assembly, test start-up and shut-down operation, which requires flexible operation and no obstruction phenomenon for many times.
