All brass valves are not created equal... BUYER BEWARE!!!
The air ride market is currently flooded with these inferior valves pictured below. They run anywhere from $15-$45 each for the same exact valve that's made from multiple China factories. Don't get us wrong - there's nothing wrong with WELL BUILT products from China, but these are not! They only work for so long until they start leaking internally. Basically, IT IS what's on the inside that counts! These are basically a "disposable" air valve. They also have a very high wattage coil that is NOT COMPATIBLE with our AVS switch boxes and they keep causing us headaches. If you are going to run these large round solenoid valves with one of our AVS switch boxes, you will need to run a 30-amp Bosch style SPST relay on each output of the switch box. Otherwise the high amperage that these valves draw will slowly damage and/or cause build-up on the switch/relay contacts, burn up traces, fuses, and more. You will also have problems when you use the FRONT/REAR/ALL UP/DOWN switches since the current draw is even greater while trying to activate multiple valves at once. We have put together a diagram below, it case you already have purchased these valves and are stuck with them (but hopefully you'll just stay away from these valves all together). We are not trying to compete with these cheap knockoff valves, so it is very important to us that we warn you. We want you to spend your money wisely - keep your sanity - and have a trouble-free air ride system. So please do yourselves a favor and stay clear of the valves in the pic below!!! You would be much better off with a DANZ, PARKER, SMC, GC or SARAI valve (which we don't even sell, so why would we lie to you?).
You work hard for your money - DON'T BUY JUNK!!! Good parts aren't cheap, and cheap parts aren't good!
