Hot Water Radiator Problem

I have old hot water radiators that all work perfectly except for one.  I have bled this unit but do not get heat.  The line feeding into the radiator is warm but this is never felt in the radiator.  Might I have a small blockage in the radiator?  If I can close the valve and the unit be snaked?

    Are you positive the valve is open???

    Older valves are a 1/4 turn valve, and when looking at them from the top, clockwise is closed. These older valves actually had a feature built into them for freeze protection. It is a 1/16" hole drilled in the gate, that always allows just a LITTLE trickle of heat to flow to the radiator for freeze protection.



    I have had one radiator with an air blockage due to someone creating an air trap by knuckle heading the plumbing, and it was a bear cat to get purged. Other than that, I've never come across one that was completely blocked due to rust. Possible, but doubtful.

    It's not so much a case of "You got what you paid for", as it is a matter of "You DIDN'T get what you DIDN'T pay for, and you're NOT going to get what you thought you were in the way of comfort". Borrowed from Heatboy.
