Can faults in the automatic control valves of air separation towers be handled online? The control valve is malfunctioning; its stroke is stuck, and it’s not possible to shut down the system. How can this be handled online?
Use some graphite powder or similar as a lubricant; it can be processed online. Set it to the manual position and that’s it.
For specific valves, specific handling is required~~Also, it’s necessary to distinguish whether the issue lies with the valve itself or with the actuator~~
