Thin film pneumatic fluorine lined flow regulating valve is a commonly used valve for flow regulation of corrosive media. It has the following precautions:

Medium selection: Thin film pneumatic fluorine lined flow control valves are suitable for flow control of corrosive media, so when selecting valves, the chemical properties and corrosiveness of the media need to be considered. Ensure that the valve material is compatible with the medium and can withstand the pressure and temperature of the medium.

Installation position and direction: When installing a thin film pneumatic fluorine lined flow regulating valve, it is necessary to choose the correct installation position and direction. Normally, valves should be installed vertically with the stem facing upwards. Ensure that the valve can operate normally during operation and that the fluid flow direction of the valve is consistent with the direction of the pipeline.

Control pressure and temperature: When using a thin film pneumatic fluorine lined flow regulating valve, it is necessary to control the pressure and temperature within the rated range of the valve. Excessive pressure and temperature may cause damage to valves and sealing materials. Ensure that the valve can operate within a safe range according to working conditions.

Operation and maintenance: Thin film pneumatic fluorine lined flow control valves are usually controlled by pneumatic actuators, so attention should be paid to the normal supply of gas source and the operation of the pneumatic system. Regularly inspect and maintain the sealing performance of valves to ensure accurate and reliable flow regulation.

Avoid vibration and shock: The thin film pneumatic fluorine lined flow regulating valve should avoid excessive vibration and shock during operation, which may cause valve failure or damage. During the design and use process, shock absorption and buffering measures should be considered to ensure the normal operation of the valve.

Preventing blockage and scaling: Thin film pneumatic fluorine lined flow control valves may be affected by impurities, particles, or scaling in the medium during use. Regularly inspect and clean valves to ensure unobstructed passage and prevent valve failure due to blockage.

In summary, when using a thin film pneumatic fluorine lined flow control valve, attention should be paid to medium selection, correct installation, pressure and temperature control, normal operation and maintenance, avoiding vibration and impact, and preventing blockage and scaling. These precautions can ensure the safe operation and long-term stability of the valve, while improving the accuracy and reliability of flow regulation.
