best valves???

My parkers popped when i hit the switch to lift it. I was running 175psi. They also barked when you hit the switch to let them down. They were pretty loud. Their more expensive but their the best. Stay away from GC's their crap.

Ive got NEW 1/2" GCs on my dually and the dump valve for the front is already sticking open untill it hits the ground. They pop when I lift it but only if the tank is full. What do the asco valves sounds like????

Everyone on here is saying how good Smc's are but I had 3 valves fail over a 6 month period. Luckily it was on my fill side, but when power was sent to the solenoid, the valves would stay open. I run a water seperator and I live in AZ where it never rains. The valves were in all different locations on the truck. I tried cleaning them and inspecting the internals, nothing helped. I switched to DANZ and have had no problems for over 2 years. Just a thought. I'd do ASCO or Danz.

SMC's had big problems if they got any moisture in them at all. Graphite seemed to help alot. GC's you have to tear apart, stretch the spring, and use graphite to lube them up and they didn't stick as much. Parkers are made to handle Gas, Liquid, and Oil. So it didn't hurt them to go without a water trap, unless it's freezing outside then the water inside the valves freeze.

I think that bark you guys are talking about the type of diaphram thats in the valve. I think when air passes over it, it will resonate. With time too, the material will loosen up and start to allow bark also... Thats why some say theres didnt do it at first. I could be way off but this is all i can think of.

Now for the pop on lift thing, it has a determining factor to it... On my rear setup, the valve runs right off the tank with about a 2ft line to the bag on the axle and the "pop" is very loud (id say almost as loud as dump running at 175psi) My front setup is much more distant I dont think they pop at all. You can hear the air pass but no "pop". By the way I use 8 FBI Blutz 1/2".

So, I think there are factors to take in on wheather your valves "bark" or "pop"

When I was researching valves, Asco's were the only ones that I found that were made to use in the elements.Industrial use ,air or liquid. Better electrical internals than most all others! I went with the 3/8" Nickel ones & use the Din connectors. No problems as of yet!!

I love my SMC's! I think that the classic loud barking sound used to be from the old school "Herion" valves.

Parkers are made for use of all the elements too.

SMCs are great. been running them for years with zero problems. old school herions/ekstensive valves are awesome too, but hard to find..
check out this ebay auction, though!

so the herions are ekstensives? i know those old herions were loud.
