RH / LH Steam Valve replacement options?
I have two apartments which became vacant recently. Each of those units has two steam radiators each. Each unit have radiators with a normal 1" angle valve and either a 1" RH (right-hand) or 1" LH (left-hand) steam valve. Since all are seized, or do not seal upon turning it shut, I would like to replace them all. The angle valve replacement is no problem as I've have already done a few replacements already but the RH/LH ones have me stumped as new replacements seem only available rarely on ebay. I would like to reach out to the community for suggestions/options for replacement!
