what kinda valves

which valves make the loud 'blowoff' sound when you dump your truck?i dont know how to explain the sound other than almost like an airbrake type sound

I think they all do pretty much, the bigger the valve the louder/faster they are...

ummmmmmm.......yeah,what he said. all of them!

i have GC 450s

iv got 1/2 inch lines but 3/4 inch valves so it move as fast as 1/2 but i have that loud ass 3/4 dunp sound

The Ascos are pretty loud.. Plus it all depends where you mount them as to how loud they are.

It all depends on the size of the valve and where they are mounted

my airlift 3/8" valves are mounted on the bags and they are not that loud. what im looking for... is kinda hard to describe, maybe i was being vague when i said air brake type sound. more like a psssshuhhh....
damnit i need sleep....

i have heard em make like a quacking sound...that's the valves i want. might just be the amount of pressure they are running, don't know

the only thing i have found different yet is the size, my 3/8's arent as loud as any of my buddy's 1/2's all smc's
