My slide seal regulator has a shut-off valve with it. So once the slide seal is deflated shut of the air. Speaking of "deflating" you will notice a vacume pump in the air circuit. This mod comes highly recommended from the Gurus on this site.
every coach i have worked on has a ball valve right at that place that steve shows. however, most have a small one with knob and not a handle like the one steve shows. i think his has been replaced. i have had to replace them on 2 different coaches as they are prone to leak
here is a picture of what is on most of them

Thanks! I installed the air pump/deflator several years ago but don’t remember seeing a valve (or didn’t install one - will check in the morning as we will be re-welding it all again :-(
