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

[Scott & Heather]

So far I've had excellent results with my self made air leveling system and I'm taking the advice of several on here and making it electric. Basically normally closed air solenoids placed strategically to allow fill and dump of air in bags. My question is this:
Are there in existence normally closed valves that also have a one-sided air dump feature? So I could just use one valve at the source airline to the bag and it would allow me to fill the bag and dump air out of the bag with just one solenoid? During the dump cycle it would have to close off the source air so that I'm only dumping bag air and not source air. Does this make sense?

Something like this maybe. Use the manifolds and resell the electronics. I have the complete valid system in my bus now and i love it.

Look at this on eBay http://www.ebay.com/itm/141834218645

This ones a bit more but it has a setup for the tag dump as well since i believe your bus uses a regulator for the tag. Mine has the tag connected to the drive axle bags.

Smokes. That's more $$$ than a handful of air solenoids.

a tee in each bag feed line...
a 4 point kneeling on one switch, or four.

Scott   Somebody should have a old Level-it kit around somewhere.  It was real popular several years ago.

if not I will see if i can find my installation instructions.

Then you can get the parts

Hi Scott

I used these  http://datasheets.globalspec.com/ds/2609/Festo/E5770A60-3669-4D76-9990-1F0796BBA67D to dump my airbags.
long time ago now so not sure if they will do exactly what you want.

And you won't go anywhere without it either 

[Scott & Heather]

Nice don I'll actually probably just use two solenoids for each bag. One for dumping air and one for adding air located appropriately on the air line.

Yeah, I can't take it with me but I also can't spend what I don't have lol. Oh wait? That's what credit cards are for lol. Uncle Ned, I'm curious now. I'll look into this. Aussie coach, I looked at the data sheet but it was all Greek to me ??

or you could do it simple like this .... zero power just 1 air line from each corner in and 1 supply .... push valve in to add air or pull the same valve out to remove air

     Clifford, is this the one?    http://www.parkersupply.com/ 

     I've looked through their listings and they have stuff like 4" dia. steam control valves for boilers but I don't see anything like what I'd need for a leveling system.
     Any more info?   Thanks,  BH

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

[thomasinnv]

Scott if you are going to retain the stock ride height valves for use during travel then you will need a third valve to isolate the bag from the ride height valve during manual operation.

One thing I like about my Valid system is if I forget to to put it in travel mode, once I reach 10 mph it switches over automatically.
