I have a back Pressure valve on my compressor set up.
It looks like a 211 valve assembly but I don't think it is.
I have compared it to a current 211 valve and it is built different.
The adjustment set up on it is different though. It has a threaded plug that screws into the top to set the pressure. It does not have a spring inside, it has washers and you can see it probably never had a spring. I'm assuming it is an older style. My question is how do I adjust the pressure. If you adjust it for more pressure it never opens. If you set it for a lower pressure it will vent through the plug.
