    Is everyone in agreement as to the great value of check valves in desuperheater loops to prevent thermosiphoning? Some of the quotes which I have looked at don't include that check valve.

    I use them in cases of more than one DSH feeding the same buffer tank.

    Quick question engineer.

    What is the location in the desuperheater circuit to place a check valve. I assume you would place it right after the circulation pump were there is a greater pressure differential when the pump is running. Correct?

    Should this be a poppet type valve with a light spring? Any recommendations?

    As you can see, I have a thermosiphoning problem.
