Dunham Packless Radiator Valve Repair

maxx · February 2011

Does anyone know if the Dunham Packless Radiator Valve can be rebuilt or if there are replacement valvles that look like the original? Most of mine will not turn and the ones that will only move about an 1/8th of a turn.

i found a crossection of the valve here:

if you can loosen the bonnet of the valve, you may be able to relubricate the inner workings, maybe using non-petroleum plumbers grease.--nbc
