So, when we are at a rest stop and only want to extend the kitchen slide, the pliers can "start" the closing process and I can safely finish it up with my bare fingers without losing any skin.

I played with the valve block before installing it. After installing and running the slides out/in 3 times to purge any air, I brought the slides in and turned the valve to stop the BR slide from moving. It was pretty stiff to turn as compared to out of the box. I am suspecting the hydraulic pressure still in the system is pushing against the valve, making it difficult to turn. I also found that there is no need to open the valve all the way (knob stops turning) to get normal slide movement. leaving it "loose" may help sticking.
I would like to know how much pressure stays in the system when full open or full closed. We have a tendency to hold the switch an extra moment after the slides are fully open/closed "to be sure". I know there is pressure as a shot of fluid sprayed out when I loosened one of the hoses to do the install. Can this pressure cause problems and will a quick reverse of the switch relieve the pressure but not affect the slide being snug to the wall?
Sure, I over analyze stuff. But hey, thats me!
I have some envy for those that have the valves factory installed. (wish we did) But I now know more about the hydraulic slide system operation than I would if I had the valves already installed.
I added this to an earlier post: Search "IRC" in the Lippert website store and all the valve units will be shown.
