looking for a special valve
(OP)
Hello,
I'm new here and I wanted to ask your help with something ...
I am looking for a valve that allows the flow of liquid but prevent air escaping out form let's say a sealed container ...
Is there such a thing?

You're not actually looking for a valve, what you need to look for is level control, the type of valve is irrelevant.
If you turn a ball cock from your toilet upside down it would do something like that

YES!
Any 'steamtrap' based on a float construction is especially constructed to do this. To get a proper answer you have to contact specialists (Spirax sarco, Gestra, Armstrong,.. a lot of others) giving details of your fluids and amounts for dimensioning and proper materials, including sealings.
Any movements/transport of the container to influence solution? Any requirements of allowable leaking amounts of air?
Note: piping layot and necessary additional components (checkvalves, isolating valves, filters) essential for a good solution.
