    Why...

    ... would you want to get rid of a modulating control valve, and go with an on-off valve like a solenoid? Even if it's sized correctly (most aren't), the solendoid will "hunt" at low loads, banging on and off repeatedly. If it's seriously oversized (most are), it'll "hunt" even at high loads.

    What is the steam safety valve setting? I see a lot of ASCO solenoids installed in systems that operate at 125 PSIG or under, but the safety valve that protects the system lifts at 150. I've never seen an ASCO rated for more than 125 steam.
