SMC 3/8th's valves not working rite

youre trying to run 175psi through a 150 psi rated valve. drop the pressure switch to 145 or buy all new valves. Smc valves hold up well. Alot better than GC250's

Mine lock up at 175 also and I cant drop the truck. But it doesnt do it often.

Alot better than GC250'sthey are not rated at 150 psi they are rated at 200 psi and according to smc and the company i bought them from should hold up to 211 psi before locking up. so 175 is way below the air pressure they are rated for.

anyone runniong the airlift valves in 3/8th's and is there any problems with them?

I have had a lot of problems with smc as well what I found is that they are very temp sensitive and once I got them to a place where they would not get cold or hot they were fine.

If you want to get rid of those pieces of shit i will buy them from you. Email me nevadahiroller@yahoo.com
