TAILONZ PNEUMATICRotary Lever Hand Valve HV-02 1/4”NPT Air Flow Control 3 Position 4 Way

Attached this valve to my semi truck cab air bags. Works amazing! Solidly constructed.

I installed this valve to individually control the air springs on my one ton ford pickup. Teflon tape didn't prevent leakage at the fittings and pipe dope was substituted. The valve works as advertised and is well worth the price.

I like the overall quality, and it feels pretty good, accurate detents. I am using it in a higher pressure application than it’s rated for and it leaked by the valve until I regulated the pressure within the specifications they advertised. I’d like to see how it’s built internally and will disassemble it eventually. Until then, I would still recommend it as long as you don’t exceed the specs.

Replaced an old solenoid valve that was expensive and obsolete

Anything over 40 psi leaks horribly!

Sturdy easy to use withstands weather and multiple manipulations of valve.

Requires 25 psi minimum

Works great as a proportioning valve for a glass lathe :)The one drawback that I wasn't aware of was that the exhaust doesn't connect to any ports - so if you want to have vacuum and pressure hooked up to the same 3 way valve, you would need a second 3 way valve to switch between vacuum and pressure.The seller answered that question when it came up quickly and I was fine with that (plus I already drilled the holes out and mounted it to some existing tapped holes haha.)I still need to get a second 3 way, for now I've just been using soft aquarium tubing on one side, which does lock into the push to connect fittings provided, then I can pop that off and slip it onto my modofoed aquarium pump for vac.
