Common faults of pneumatic fluorine-lined valves include the following:
OneRegulate valve leakage:
It may be caused by poor sealing of the valve seat, aging or damage to the gasket, damage to the valve stem sealing ring, etc. The solution is to replace the seal or adjust the sealing face of the valve seat.
IIThe valve is stuck or won't open:
It may be caused by damage to the internal structure of the valve, poor sealing of the valve seat, insufficient air pressure, etc. The solution is to repair or replace parts depending on the specific cause.
IIIValve slippage or leakage:
It may be caused by insufficient air pressure, poor sealing of the valve seat, and excessive operating temperature of the valve. The solution is to increase the compressed air pressure, replace the seals, or lower the operating temperature of the valve.
FourthPneumatic actuator failure:
It may be caused by the failure of the pneumatic drive itself, damage to internal parts, etc. The solution is to replace the pneumatic drive or repair the internal parts.
FiveThe valve is unstable when it opens or closes:
It may be caused by unstable air pressure, damage to the internal structure of the valve, or failure of the pneumatic actuator. The solution is to adjust the compressed air pressure, replace the internal parts of the valve, or replace the pneumatic actuator.
The above are the common faults and solutions of pneumatic fluorine-lined valves, which should be repaired or replaced according to the specific situation.
