They (the XL)are for .625 valve openings so yes. I can not tell you if any of our valves have been used definitively on semi trucks.
I can say I do know they have been used on backhoes, large and medium sized tractors(installed a few of those myself), skid steers, and I’m almost positive they’ve been used on Dump Trucks but again, not 100% sure on that one.
I know of customers running 80 psi, lab testing our valves didn’t fail until much, much higher than that. Lab test results on our page.
A minor issue is this is assuming the valve is installed sufficiently, they need to be tightened down snugly enough to expand the gasket, but even though you CAN keep tightening, that’s where you can damage the gasket.
We rarely , if ever to my knowledge, run into an over tightening issue with our Emergency Valves, as they are tightened by hand via wing nut. It’s the Ultimates//Permanents/XL where it happens occasionall, mainly because once you put a socket wrench in ANYONES hands, the tendency to try to crank until it won’t move is human tendency, I’ve done it myself

.
I now use a 1/4” spinner drive to tighten them down personally rather than a socket wrench.
hope this long rambling reply helps? I have a tendency to run long
