radiator question re: Supply Valve and Tee

in Strictly Steam
In a cold bedroom, the radiator is about to have the supply valve changed by a plumber.  I believe it to be faulty because the valve will get piping hot, but nothing gets into the radiator.  My question is:   if I were to have the valve installed, but , between the new valve and the radiator, would it be ok and beneficial to have a reducing tee installed.  The third port on the tee would face up and have perhaps have an added air vent on this tee.  Would this work? Would it help to drive more steam up to this problem radiator????

    ok then

    I had the exact same experience and was hell-bent on replacing a supply valve and was talked out of it on this site.  

    instead,  i took the bonnet off the top of the supply vavle and basically disassembled the top side of the valve, removing the disk that moves up and down to close (it will make it so valve is wide open all the time). 

    my problem went away.    I no longer have the open and close functionality of the supply valve, but the radiator heats up now where as the heat always stopped right at the valve before.

    try that first maybe?

    only purpose for valve

    The only purpose I know is to shut off heat if it's too warm.

    I don't know why butterfly valves weren't used starting in 19th century.

    They're the cheapest.

    Open vent test

    Changing the valve will not necessarily improve the steam flow into the radiator. Have the plumber take the bonnet of the valve off, and see if the disk on the end of the stem hase become unscrewed. As the valve is only to be used for service, the disk may be removed, if it is unfixable. Changing a valve could be several hours of hard work, as the old spud must be removed, and the new one put in for the new valve.

    Test the radiator by switching the boiler off, and then removing the vent. Turn on the boiler, and set the thermostat higher, to see if steam will come out of the vent hole. You must be able to switch off the boiler as soon as steam is seen.

    I suggest you go back and delete your duplicate posting to make things simpler for others who may have something to add to this thread.--NBC
