@DurangoTaB and @Tabaz - I wasn't thinking I'd be constantly adjusting the valve. Instead, I'd just try to get the valve set so it approximates the opening in the Alde high altitude switch (and/or sufficiently quiets the rumble), and then hopefully forget about it.
@ChanW - you're a braver man than me. I personally don't have the tools or expertise to attempt to modify a ball valve in such a way that I'd trust it.
I looked at a 1/2" FIP ball valve at HD yesterday, and the label specifically states "Use only in a fully opened or closed position". I'm guessing that having the ball valve in a partially open position allows gas to enter the body of the valve, so you'd then be relying on the seal around the stem to prevent leakage. Note that drilling a new hole in the ball would result in the same situation.
To further muddy the waters, a guy from a local HVAC company was passing thru the aisle at the time, and when I asked him for an (informal) opinion he suggested that it wasn't really a problem - they often see ball valves used in this way and the stem sealing prevents leakage. He did also recommend using a metering device to gauge actual pressure/flow - probably because fine-grained adjustments are difficult with a ball valve.



I didn't really get the freight train until above 9,000'.Verna said:@SAM, no, I do not have the mod. I’m at 5300’ (give or take s few) and no freight train here either. I’m taking my time going home because it’s going to snow again tomorrow!
I’m just reinforcing what others have said. The freight train doesn't occur on every Alde. No, I do not know why.
