ive just showed the pot and choke valve fitted on the air pipe half way downThe choke valve runs down the back from the Tee where the supply air comes in.
The hose on the choke valve supplies air to the underside where the sand drops down thru the sand valve.
If you close the choke valve, more air goes on top of the sand.
I'll try to dig up a diagram or pix tomorrow, I think Clemco has a nice diagram.
