Old problem
Thread Content
Another winter has arrived. I would like to ask: have you taken any measures to prevent freezing of the control valves in the system? Or do you just leave them as they are after completing the pipeline purging process?
Do you mean a system that stops? ? The water inside needs to be drained; there’s nothing wrong with the control valve!
Make sure to drain all the water inside! Especially fluorine-lined valves
When not in use in winter, drain the liquid and dry it out. For particularly important valves that are not used for long periods of time, removing them for maintenance is the best approach
