I'm tracking leaks on my air system and am trying to understand the schematic symbols.
On some of the lines, there is a rectangle with an arrow inside. Is this the symbol for a check valve? Is the symbol for a junction in the line a circle or half circle around the junction?
Thanks,
Rich
The rectangle with the arrow is a check valve.
Just above the HWH compressor is a four way of different size tubes.
From the front brake tank there is a safety valve then a three way connection of similar sizes then a check valve and then a four way of same size tubes.
Looks like a T with a check valve coming into the tank on the left. And a two way check valve T (one way out) on the top of the tank.
No symbol reference so these are what I have been using. My best guess.
Thanks Roger.

I am trying to understand my air schematic and hope someone can help me with the symbols and notations used.
I assume that the arrow in a rectangle represents a one-way check valve. What is the meaning of a number in a box on an air line? In the air suspension sub-system I assume that a circle with an adjacent number in a box is an air bag.
Am I correct in these assumptions?

Thanks, Michelle.

2 That is your air line # designation all your air lines should have a sticker on each end that should match the ones on your prints.
3 Our air bags are a letter "S" in a circle on our prints but that is for a '97. With yours being a '01 they may have changed the labels. The air line that feeds the air bag is labeled with a number in a box like the rest of the air lines.
