Ventilation Butterfly Valve Low Torque Pneumatic Electric Regulating Valve

Zero Leakage Ventilation Butterfly Valve, Low Torque, FB-Q Model

 Pneumatic Electric Regulating Valve

1. Description:

Zero leakage ventilation butterfly valve, low torque zero leakage valve: the ventilation butterfly valve is a non-airtight butterfly valve, widely used in building materials, metallurgy, mining, electric power and other production processes medium temperature ≤300℃ nominal pressure of 0.1Mpa on the pipeline, used to connect, open and close or adjust the flow of the medium.

Ventilation butterfly valve is used in the cold air or hot air gas pipelines containing dust in the ventilation and environmental protection projects in the chemical industry, building materials, power stations, glass and other industries, as a pipeline control device for regulating the flow rate or cutting off the gas medium. This type of valve should generally be installed horizontally in the pipeline.

2. Specification:

3. Features:

• Designed and manufactured by using the new structure form of welding between the middle line type butterfly plate and the short structure steel plate. It has the advantages of compact structure, light weight, easy installation, small flow resistance, large circulation, avoiding the influence of high temperature expansion and light operation.
• No connecting rod, bolts, etc., reliable work, long service life. Can be installed in multiple stations, not affected by the flow of media use.
• Ventilation butterfly valve is a non-airtight butterfly valve, widely used in building materials, metallurgy, mining, electric power and other production process medium temperature ≤300℃ nominal pressure of 0.1Mpa on the pipeline, used to connect, open and close or adjust the flow of the medium.
• Adjust the flow: The ventilation butterfly valve  can control the flow of gas or liquid by adjusting the opening of the valve. By changing the opening and closing degree of the valve, the flow rate of gas or liquid can be accurately controlled, and the flow rate in the pipeline system can be adjusted.
• Adjust the pressure: The ventilation butterfly valve can also adjust the pressure of gas or liquid by adjusting the opening of the valve. When the valve is closed, it can effectively prevent the flow of fluid, thereby increasing the pressure of the pipeline system; When the valve is opened, the pressure on the piping system can be reduced.
• Stop fluid flow: The ventilation butterfly valve can be completely closed to stop the flow of gas or liquid. This is useful in certain situations where the flow needs to be stopped urgently, such as dealing with an emergency or repairing a pipeline.
