[TheForge] AFC Air Scheme

Sun Mar 30 18:19:00 2003

Well to me its made it a different hammer. I have a 2 1/2" cyl 100# ram and
2 limit switches. The way I did it is I put a 3 way ball valve on the outlet
of the 5/2 valve to the top of the cyl. this way I can have full force/flow
blows or at a flick of the 3 way ball valve I have faster, lighter blows via
the pressure control valve, I get 230 or so BPM through the pressure control
valve, slightly less the other way. I think it helps also with air
consumption. I wouldnt build a hammer without it, although when I was using
a 2" cylinder I tried it and it didnt seem to have quite the same effect.
