@John_Martinez, I’d consider a video after it’s all done, but that’s still a ways off lol. Getting closer though. And thank you for your kind comments. I appreciate it.
@Racer, I hear you on the 1" being large. It is large. And expensive. Got new quotes today for the new generation of the Chemline valves, and their pricing went up significantly, which that alone may rule out the 1" option, at least in my opinion.
As far as 1/2" not flowing like it 1/2" should, I think this is the problem…
Metering valve linear v-groove ball:
Metering valve fully open:
Metering valve fully closed:
As you can see, these do not look like regular ball valves. Breathing though one fully open isn’t like breathing through a 1/2" pipe. It’s restricted. There is resistance. You have to actually suck in air and blow out air. This is why I think running tests with various sized systems would be best, because it’s not simple math or pipe flow charts for these valves. For instance, I don’t think you’d get the same distance/flow with a singular ball valve fully open going into the diaphragm pump vs a single metering valve of the same diameter fully open going into the diaphragm pump. I haven’t tested this, but I’d like to.
@cleanunderpressure, show me the quick math? Lol. It’s actually not that simple, in addition to the information shared above about the v-groove ball in the metering valves, you have this to deal with: The area of a circle is A=πr^2. That means it’s an exponential relationship based on radius, or half the diameter, and that assumes a full circle (looking straight through the valves). But it doesn’t close or open perfectly with respect to all that, plus you don’t truly have that cross sectional area because of (see above photos). So there might be some math to aid or get the general idea. I did do an excel file with some math for ratios and area, but that’s just to get ratios based on valves open. Not actual area open for fluid volume to flow through, so it doesn’t really apply in terms of “where did my distance or gpm go?”
