Oil, gas, and steam are leaking from the valve core of our unit’s special valve; I’m not sure if this can be fixed

If there is air leakage at the packing, it can be tightened slightly, but not too much; otherwise, it will be difficult to operate the valve, and coking may occur if it isn’t tightened properly.

It was close, but it didn’t work. Thanks for the advice

It’s not too easy to carry out repairs during operation; thorough maintenance can only be done when the system is shut down
