Hissing Radiator

Hi All. Please excuse me if I don't use the right terminology. I have Steam heat with recessed radiators. On one end of the radiator is a kind of release valve. When the heat is on some of the radiators hiss alot ( really loud), some a little and some not at all. Can Someone tell me what is normal and how to correct if there is a problem.

Thanks

The release valve you are referencing may be an automatic vent for venting air out of the radiator. Is it on the side of the radiator at the top?

I have not seen one in many years, but the ones I am familiar with were egg shaped and chrome colored. Does this describe your "release valve"?

Hi Rick, thanks for the reply...sorry I didnt respond right away.. Yes that describes it perfectly... I read somewhere that when the steam hits these valves they are suppose to close. Im figuring that mine are stuck open...Just wanted to get some feedback. Maybe I should replace.

Thanks

Yes, you should replace the auto-vents. You do not need to drain the system to do this, just shut the heat off and let the radiator's cool some.
