(OP)
In a single pipe steam boiler system how important is the steam valve on the radiator. If the valve was removed from the radiator and plugged would the rad still heat up, if so to what degree. The system runs at 2 or 3lbs.

Are you talking about pugging the vent on the condenser (radiator)?
RE: single pipe steam boiler
If the vent is plugged there is not way for air to exit the radiator as steam tries to enter, hence no heat.

If you are really courious about a particular radiator, plug the vent and try it. It won't hurt anything.

The book I mentioned in a previous post "The Lost Art Of Steam Heating" describes all of these old systems (and there were many designs) far better than I ever could. And it's written by a guy who can tell an amusing story, so it's not like reading the phone book. Some of these systems were amazingly simple, yet worked flawlessly. Others incorporated very sophisticated controls - like one that sense the draft up the chimney, and throttled air dampers to keep the coal fire going all night. And it was ALL mechanical - no electrical components at all. There were some truely gifted people designing mechanical systems 100 years ago.

Right, pressure drops back to atmospheric. In the off fire cycle the air vents don't forcibly introduce air, they just prevent a vacuum from forming.
