The steam valve is not opened or closed frequently – what should I do if it can no longer be closed?

Since the steam valve is not opened and closed frequently, what should be done if it can no longer be closed? Thank you
Spray some loosening agent on the screw to see if it helps; if that doesn’t work, the valve will have to be replaced
Apply some oil to the valve stem, open and close it several times; it will gradually start working. Give it a try.
Regularly refuel and maintain it. If it won’t close, you can use a loosening agent and operate it open and closed several times.
If there’s really no other way, you can ask the people in the engineering department for help in finding a solution; try not to use an F wrench or a lever to force the switch on or off
Add the padding agent, soak it for a few days, and then unfurl it slowly
Spraying a little loosening agent on the screw and internal thread should work. Be careful not to force it open or close.
Since it wasn’t properly protected, it’s generally not advisable to apply oil to the steam valve; the oil will actually cause scaling when heated. If I remember correctly, something like graphite powder should be used instead. For now, the only option is to use an F wrench to turn it slowly.
Sprayed a loosening agent on the screw and internal thread; neither bottle had any effect. The temperature of the valve was high, so the agent evaporated as soon as it was sprayed, and even using an F-wrench didn’t move it.
Apply some butter, wait for it to melt, and then try using an F wrench.
Apply some lubricant to the valve stem and the packing; once the lubricant has penetrated, everything will be fine. In the future, apply some lubricant to the valve stem and the packing to prevent such problems from occurring.
The valves in this system are indeed not operated frequently; if it is difficult to open or close them, the key is to focus on lubrication, using grease with strong loosening and penetrating properties for lubrication.
