    Solenoid valve ?

    Why would you install a solenoid on a equalizer line for a hgbp valve ?

    No , I know you need one there for isolation when you have a LLSV this is on the pilot tube -equalizer line

    Theres no reason to put a SV in the equalizer line.

    What controls the SV?

    To turn the HGBP off would be my guess.
    UA 100

    It takes three people to do anything around here. Two do the work, one explains to the crowd of people who showed up when they seen smoke and flames.

    That's done on the hot gas bypass line itself.

    A picture sure would help, cause it isn't making much sense to me why you would do that.

    Would you give me the same answer for a TXV? For capacity control in multiple TXV applications coil?

    Are you asking about a EPR ?

    Nope a plane ole TXV . What's going to happen to the TXV if we turn the equalizer off to it?

    Your going to lose one of the three forces operating the TXV. Has nothing to do with hot gas bypass. Show me one piping diagram for hot gas bypass using a solenoid on the TXV equalizer line.

    Is that even possible what if you don't have a MLV on the circuit?

    Well now the OP never did say what application he was looking at. My guess is a freezer which should have a CPR. As far as a MLV (minimum load valve ) I would expect to see one of those on a chiller application. There the MLV equalizer line would be teed into the TXV equalizer line. With a solenoid on the discharge side of that valve.
