valve problem

I just swapped a nitrogen bottle in my truck and have been running it around 150 psi. Everytime I go on a long drive it seems that my front gauge would read about 20 pounds more than what was in it when i started. So I left the truck sitting with the bottle on and checked it an hour later and about 20 pounds had leaked into my front bags. Anyway to fix this? Or do I just need to get new frotn valves? Thanks.

Do you have check valves in the system anywhere? Sounds like maybe a valve is sticking open, try and clean them!

had the same problem and i tried to clean them and every thing and nothing worked i just got new ones

your valve maybe stuck open, oil the valves. because, I have the same problem, as we speak!

but if they are stuck open, then wouldnt they just fill right up with a 150 shot of nitrogen?

leaky diaphrams... .what brand valves?

could just be a slow leak

lemme guess GCs? I know some of there valves had this trouble...if you turn your pressure down they will quite leaking.

Try to take them apart and clean them. If that dosent work buy some Parkers or ASCO's. Parkers are expensive but everyone I know who has them has never had a problem with them. I use ASCO's and have never had a problem yet and there cheap! Good luck

They are alcon valves and you cant clean them because they are the 2 in 1 valves. Ill prolly just get some new ones.
