In the evaporation crystallization process, due to the high chloride ion content, what kind of valve material should be used?
Thread Content
For example, what kind of valve should be used for the outlet of the evaporation crystallizer? The temperature is high and it contains high chloride ions. I originally wanted to use a fluorine-lined valve, but the manufacturer said it should not be used too much. The crystal particles will cause wear to the valve core and cause it to not seal!

2205, titanium, or steel lined with PTFE
A valve made of 2205 material will suffice.
There are still many available, but ceramic valves are relatively economical and durable, while other titanium and zirconium valves are too expensive. If the temperature is not too high, fluorine lining is also possible.
