<div><br>
</div>
<div>For the MFCs we ordered them with welded on 1/2” Swagelok compression fittings.</div>
<div><br>
</div>
<div>The potential issue I see with the solenoid valve is that for the larger size pipes is that (at least so far) they have a minimum operating pressure differential, whereas the smaller sizes don’t.</div>
<div><br>
</div>
<div>Is there any reason we couldn’t go with a 1/4” NPT fitting on the solenoid valve and just use adapters to 1/2” compression? Which is what we were planning on using with the MFCs initially. There’s some even lower power Asco valves/coils if that is okay.</div>

The fan that I tested is a little small, so I was planning on testing some others when we have the system put together. My thought was that if a fan does not work, then we could always use a 120 V diaphragm pump left over from the old DC system - we should
have 6 of those pumps left.</div>
