Air suspension questions..... :)
Hey everyone, ok I am mainly having a little bit of trouble with my air valves. Ok Can someone please explain to me the importance of the air lines in your system. Ok say I have a 3/8" thread valve with 1/2"fitting to the air lines then would it be different if it were with a 1/4" air line instead?(slower?) Also say I got a 1/4" thread valve with a 1/2" fitting to the air line, than how would that react? The reason im wondering all of this is because i have airbags and 1 of my valves are failing(down on back right, it loses pressure but very slowly) and im not sure if I want to replace that 1 valve or just downgrade all my valves to 1/4" so the bags are slower and I have more control. Thanks everyone.

Rep Power: 0 are you sure its the valve that is losing pressure ? most likely it is a leak in the fitting causing the bag to deflate. valves very seldom break and if they do you just have to take them apart and replace the rubber diphram. what company valves do you have ?

Rep Power: 0 Its a parker 3/8" valve, and the back right dump valve is screwed up(f.b.s.s setup) it deflates but does so VERy slowly, so say i bring all my bags up all the way to full and pressed for all bags to go down then the b.r. would be a lot higher than all the other sides because that valve is deflating but doing it very slowly.
On the description of the valves it say " Parker 3/8 Thread 7/16 Orifice " for example, im guessing 3/8" is the threading into the valves, but what does 7/16 orifice mean, and what is the orifice(size of the opening of the valve?)? Thanks.

Rep Power: 0 the orfice size is the actual size of the open inside of the valve thats why theres a slight bulge on valves. you should be able to get replacments for your parkers they are the most popular company around.

They go in the end of your valves... basically reducing the size of your dumps... air can only travel as fast as the smallest orifice on your setup... you would still have the lift just as fast, it will just slow down your dump. << this would be the inexpensive quick fix.
Oooooooor you could, instead of re-running all your airlines, just get 4- 3/8" valves and swap those with the dumps that you already have. They're like 29 bux each $120 total. 10 minute swap, nice control, does nothing to the lift. As opposed to swapping airline, 50/100 ft = $39/78 (+ the cost of all new fittings), at least a few hours to run (also a pain in the ***), and it'll slow down your whole setup unless you're just planning on running smaller lines to the dumps.
*edit- if you're running 1/2" line on 3/8" valves, going down to 3/8" airline would be good enough... 1/4" would be hideously slow

About the 3/8" airline, you have to remember the measurements are taken as outside diameter. When you couple 3/8" valves with 1/2" airline, the point is to make the internal diameter of the airline as large as the valve itself. If you use the same size lines as the valves, then the internal diameter of the airline will be approx. 1/8" smaller, almost equivalent to 1/4" I.D.
Hope I cleared things up for ya
