Self leveling valve and ■■
Air brakes are isolated from suspension last time I looked.
every trailer must of been built wrong that ive been out to with a burst bag then as the spring brakes have applied after the driver has stopped must inform C/F ,WILCOX SDC,DONBUR,WEIGHTLIFTER(RUBBISH),KELBERG ETC ETC. thanks.
One of them cases where you’re both right and wrong .
Lose all your air and the spring brakes come on. So although isolated, a catastrophic loss of air tends to stop the job.

Well you talk crap.Look on the tanks and you will find a predominance valve.This allows the brake tank to pressurise to 9 bar to relieve spring brake pressure before supplying air to the bags.Also if a bag or bags fail it stops the brake tank dumping air and applying the brakes.Keep up eh my “professional” collegue.
Jesus wept no wonder the job is going down the pan.

No you won’t.
At least it won’t be a predominance valve that you find there. A predominace valve (when set up), and normally fitted to the unit, delivers a higher pressure than the signal pressure it receives.
What you should find is a pressure protection valve or a charging valve which does ’ protect’ the braking system reservoir, by ensuring that a loss of pressure in the airbag circuit does not deplete the braking reservoir.
Like many things there is more than one way of achieving a desired result; if there wasn’t we’d still have DC charging systems.
When I have time I shall look up my old course notes about the MAN model between the HT and the F2000. This had what I vaguely recollect the trainer calling an ‘overflow valve’ in circuit downstream of the airdrier. This, I think was supposed to deliver 14 bar for the air suspension, and 10 bar to the braking reservoirs… but I could so easily be wrong, which is why I intend to look it up.
I did ask him how much of a ■■■ he wanted to keep making of himself when he first came out with ‘predominance valve’ but, no still kept ploughing on with it.

Predominance gives you the clue monkey the brakes have “predominance” over the suspension.Keep up ffs.

Thats a relay valve genius.As in a transistor small input large output.
