The pressuretrol on my one pipe steam system has a main scale cut-out rangeing from 3 to 12 psi, so i'm asuuming that it can't be set to a lower pressure ie; 1/2 or so. Is this correct? do I need to rplace it? Thanks.

Can anyone
recommend one? Dan seemed to suggest in "the lost art" that perhaps the vaporstat would be the way to go but is it worth the cost? thanks0 -
Name or number?
of the pressuretol. Just to add to confusion there were additive and subtractive scales. Or could it be .3 to 12? Is there a differential scale inside the pressuretrol,what is the scale on that?0 -
This pressuretrol
is a honeywell PA404A 1025 2. Main scale cut-out, 3psi-15psi.(.2kg/cm-1.0kg/cm). The differential wheel ranges from 1-5.SO this a subtractive pressuretrol? Would this system perform better with a pressuretrol that has a cut- out at a lower psi., say 1/2 psi? Thanks0 -
is this a house?
than a vaporstat would probably be the route i'd take.0 -
Yes,this is a house.
80 years old,original piping but boiler has been replaced about 12 years ago.I read about vaporstats and Dan mentioned them in LOST ART, but they are kind of pricey.Not afraid to spend money if it's the way to go though.0 -
well, steam moves faster at
lower pressures. also customers tell me their systems are quieter when ive replaced their pressuretrols with vaporstats.0
