Radiator Valves

Just wanted to know which brand of Steam valves is most highly reccommended by the experts here. I have to replace some 3/4" and 1/2" radiator valves. My local plumbing distributor sells Legend Valves. Is there a preference in the HVAC community among steam experts? This is for 2 pipe steam BTW. Thanks

    Why replace?

    These valves are pretty easy to maintain, so try to keep the old ones if you can. If this is on a 1-pipe system, the valves should be always open.

    At the minimum, the packing around the stem may need to be renewed, and at the most, the bonnet may be removed, and a broken washer, replaced.

    The trouble of getting the old spud out, and putting the new one in for the new valve is a real chore, and best avoided.--NBC

    must replace

    They are 2 pipe steam as I mentioned. They are very old and do not have packing nuts. They are 1930's Warren Webster valves. They also do not use the standard replacement discs. The parts are obsolete and I have to replace them. No other option.

    sells rebuild kits for many Webster valves that may allow you to fix 'em without pulling that radiator spud or even removing the valve body.  The only hard part would be removing the bonnet itself without distorting the valve body.

    Valves

    If you replace them, I'll buy them from you. I have a customer with a Warren Webster system looking to take out a few modern valves and install some originals.
