    Why?



    7 Ton trane split HP.

    Double check valve?

    Only thing I can think of was that they didn’t want to have to build A larger single one, and so just pulled two small ones off the shelf.

    It looks to me like Trane makes their own check valves like these. The smaller size likely satisfies the majority of their production needs and it's probably more economical to parallel two of them for larger tonnages than to produce and stock a bigger valve for the larger units with lower sales volumes.

    They could also be buying thousands of the smaller ones at a great price, whereas a couple hunderd larger ones may cost way more than twice as much.

    Am I wrong, or does that "conflaberartion" appear to be newer than the rest of the piping in that unit?

    I was thinking the same. My first thought was mufflers we’re there then removed but after looking at the piping that would not make much sense either.
