B109BL Check Valve

by Ruben Pina Sr
(San Antonio, TX)

I have an old Sanborn Black Max B109BL300-2 compressor.
I just replaced the pressure switch and now I realize that I need a check valve.
Iv'e taken the manifold off and don't even see a valve ball or whatever is supposed to be in there on one side of the spring.
Do you know where I can get a check valve that goes on this compressor / manifold.
I think the model is 3HP, 8.6 SCFM @ 40 PSI
Model: B109BL 300-22-SWC

Hey Ruben... when you say you don't see the check valve in the manifold, if I'm guessing correctly as to where you are looking, it's not there.

The tank check valve is typically located at where the line from the pump enters the tank.

Please see:

Once you have your tank check valve removed, Google compressor tank check valves, and pick on of the many you will find that matches yours.
