Air going through

We are using pneumatics and our air is leaking through, I’ve done everything I know to do. There are no leaks, the air tank is connected to the switch, which is connected to one of the controllers that regulates whether or not air goes through. It is going through the regulator even though I have everything hooked up correctly and the program is set up properly as well. Any suggestions?

Can you send a picture of your pneumatics? Can you hear air escaping? You say it’s not leaking and then that it is so could you please elaborate .

My team experienced the same thing try switching around the ports of the regulator, That was the problem for us.

Yup, the regulator seems to work better going one way than going the other way. It doesn’t make much sense but just switching things around seems to fix most leaks like this. That, and adding some teflon tape to connectors helps those to not leak.

Make sure the air from the tank goes into the bottom port on the regulator (away from the adjustment screw).

The top port (next to the adjustment screw) is the output.

I will when I get back to it. Air is going through the regulator and to the tubes fine, the problem is that it is going through the regulator even when the code is supposed to prevent it from doing so. I know it is not leaking because the air is coming out where it is supposed to, it is just going through the regulator when it is coded not to.

Do you mean the regulator or the solenoid? The regulator has 2 ports and a knob-like thing to limit air, the solenoid has 3 ports total, 1 for input, 2 for output (or 1 for output on single acting pistons).

If you could attach images that would be very helpful. The

We had a similar issue and I recommend pressing and holding the blue button all the way and then releasing. Also look through this article to check if your solenoid is wired with the correct tubes in the right places .

Hmmmm. Those statements seem contradictory.


Another thing to check if the solenoid is leaking is make sure the screws holding the solenoid together are tight. There are a couple of very small phillips-head screws on the top and bottom of the solenoid.

Using the correct size screwdriver, make sure they are snug (they are SMALL, so they do NOT need to be super-tight). Tighten them until they stop turning, then nudge it a tiny bit past and STOP.

If these screws are loose, the solenoid will leak air out of the seams where it is put together.

They can become loosened if you mount the solenoid using the bracket on the bottom to a piece that moves back and forth.

Guess how I know this…
