    could use way more information....explain the whole system. Unless this is used to heat half of Manhatten, or the steam is needed for manufacturing, its way too high...
    The 7psi is probably a manual reset hi limit.
    post some pics...
    Same goes for the other website, but post in Steam section

    The one set at 7, is a code required second pressure control. the first one, is set to high. Probably because the boiler makes steam too fast. And the far radiators weren't getting any steam.
