Betta is against hooking the solenoid after the metering valve but with the Parker H3, I like the looked of it being before the solenoid and it is easier to turn and read the knob on the valve. It has been running for about a month or 2 now with no problem. Here is my setup that i hook it up to a cerges reactor
the cavity space is small between the solenoid and the metering valve, so I guess it is ok.
but I am not sure why you want to hook it up this way, swap the places of them it will be better.
