Is there an electronic air valve with dump feature? Air leveling question

[TomC]

Because I wanted to retain my automatic leveling valves (helpful in cross winds, etc) and because I believe in keeping the original 3 point leveling system (to eliminate possible twist), I used three Red top 12v air solenoids at each corner.
Between the automatic leveling valve and the air bags, I spliced into the air line a normally open valve so the air could still flow through. Then between the air leveling valve and the normally open solenoid, I Tee'd in 2 more normally closed solenoids-one for adding air, one for exhausting air. The operation is activate the normally open solenoid to close it, then can add or exhaust air. These solenoids are continuous operation, so when I'm camping, I can leave them in manual mode if I need to level. Each position I have an on/off toggle to activate, and an on/off/on momentary switch to add or exhaust air. I can get at least 4 days before the bus finally settles down. Have had good success with this system, no problems. Good Luck, TomC

I was wondering when someone would add that the leveling system needs three solenoids so you can use the factory leveling system while driving and the parked levelers when camping.  Some inexpensive solenoids are the ones used to shift 2 speed rear ends.

i figured he already had that part...cuz he drives it places

Bruce, www.parker.com  Parker/Hannifan has any type valve you need

    Thanks, Clifford.  That's just what I needed!

I assume you meant to say "between the AIR BAGS and the normally open solenoid"? Otherwise the levelling valve would just readjust the bag height automatically.

Or do you adjust your air and then close off the no solenoid? I suppose that would work too though less desireable of a setup imho.

Thanks for the Parker site cliff. Truth is, I've been running for almost a year without my OTR leveling system. I removed all of my auto levelers and have been running manual leveling 24/7. I love it. My bags don't settle at all.  They hold pressure for months. So once they are set for driving, they are set. I adjust for road crown sometimes or heavy side winds but for the most part I set them and forget them. So yeah I just need add and dump air solenoids. Simple. Dave you system is pretty cool and simple too. I just am trying to keep the air lines/fittings between the bags and solenoids very small and minimal so I don't introduce future leaks

I went the other way just air ... 1 connection at the bag the other at the valve at the drivers seat no breaks in the air line . zero problems for 10 years

Thats how I did the MC8. Just manual system and worked well. I wanted to retain the automatic valves and the high rise on the DL3 so I went with the electronic system. I bought a complete system from Valid Manufacturing, took about a day to install.

I'm still searching. Maybe there's a term for these I'm not aware of. Basically I want this: supply the air from one direction when switch is flipped up. And when the switch is flipped down, exhaust the air from only one direction to deflate the bags. This must exist.

run tee
the feed and exhaust should both be NC. activated by momentary switches.
if you are using electric.
the air sw. above is an air seat height adj valve...pull to add and push exhaust,no electric involved...you just need to pipe the exhaust away. (or vice versa,push-pull).I am getting old timers disease, i forget easily

then there are these...

I typed in "3 position air switch" on eBay and got several hits. Actually, look for 3 position electric air valve so you can control it with a remote toggle switch.

Fantastic. Ok you guys got me on the right road again. I was struggling with the terminology. Now that I know what to search for It helps. Those military surplus switches I think could work. Just trying to figure out if they vent just one side. But again, I'm on the right road now. Thanks Geoff for the terminology. I'll be researching this.

Scott be carefull about pressure rating on those. Some will only hold back so much pressure with zero pressure on the other side, and some will only "pop" open up to a certain pressure differential between the two sides.

Before I  got the Valid system I bought some solenoids that were supposed to be rated for high enough pressure but they ended up not working right for tha application.

I don't know how it works for sure really never looked into it,the Humvees we have use a air system that should work for Scott.I cannot see a 3 way valve working without a distribution center or block , or a 4 wire valve
