Steam trap repair/replace

Unknown

replacement Cage Units and Covers are probably easier to obtain. According to their literature, the 1A and 1E Dunham Bush valves take the 1950 Cage Unit and also require the Model "A" Cover. Some 1E's had Integral Seats and some had Removable Seats. I remember being involved quite a while back in a job where the 1E valve bodies were a variant that the 1950 Cage Units would not work in. That guy ended up replacing the complete valves. Hope this helps.

Steam Trap Repair

All the steam traps in my two pipe steam system are either empty or they do not work. Some are the Dunham-Bush 1A & 1E and some have Barnes & Jones '1950' Covers - seemly been updated earlier as the main bodies still look like the Dunham-Bush. I was planning on getting all new covers and getting the repair cages from Barnes & Jones even though all the Main Bodies are from Dunam-Bush. Is there any quality difference between the B&J or the D-B steam trap guts?? Would there be a functional problem with a D-B main body and a B&J Cover and Cage Unit??

Thanks in advance for your help!!

Barnes & Jones makes replacement trap elements for most steam traps. With some traps, when using the B & J element, you must also replace the cover. Once you replace the cover, I think you have to stick with the B & J element, unless you purchase an original Dunhan-Bush (now Mepco) cover.

Another good manufacturer of traps and replacement elements is Tunstall Corp. http://tunstall-inc.com
These are the ones I would want in my house.

Hope this helps,
