Mine is working abnormally. When hooked to trailer and pressure on air bags rises it opens up and leaks.
What is it called?
What is valve called that releases air from airbags on tractor?

It doesn't release air under pressure though. Do you have s pic where it's leaking?
Rideandrepair Thanks this. -
So, I have previous posts about my truck having problem with my air dryer. When going uphill it is working fine. As soon as I start descending, purge valve on airdryer starts purging every thirty seconds until it stops (I don’t know why… overwhelmed maybe) and air tank pressure goes up to 145 psi until Safety Valve starts releasing air. Yesterday at dark I stopped to take a look and something is leaking somewhere in rear suspension area.
My guess is at uphill angles this leveling valve is fine but leaks at downhill which would explain why purge valve starts kicking every 30 sec or less.
Is my theory realistic because I’m changing leveling valve tomorrow? Or am I wasting money?Rideandrepair Thanks this. -
Is it making a rapid tsk, tsk, tsk noise repeatedly until your alarms come on for your air pressure?
Rideandrepair Thanks this. -
When I’m unhooked from trailer,

So get under there with some soap and water and find where it's coming from. To me it sounds like a leveling valve. It will exhaust air out of it if the o ring inside is shot
Rideandrepair, Forever237 and 77fib77 Thank this.
