STARTER VALVE PROBLEM SOLVED

[Trainman4602]

Some of my customers have been having problems with the starter valve. This is do to the use of a square section "O" ring. The incoming steam catches the edge and pulls it off.

I thought the this style seal would work and it did under a hydro test. Evidently under steam is a different story.

I originally used a regular round section "O" ring that worked over hundreds of cycles with out problems.

If you are having problems of the seal blowing off please PM me and I will send you the round section type.

Thanks Dave

PS I will be at a meet in Canton GA for a week so I will address this when I return.
