Air Controls
• Main air ball valve (BA): turns air on and off to the
system. When closed, the valve relieves pressure
downstream.
• Ram air regulator (BB): controls ram up and down
pressure and blow off pressure.
• Ram director valve (BC): controls ram direction.
• Air motor regulator (BE): controls air pressure to
the motor.
• Air motor ball valve (BF): turns air on and off to
the air motor. When closed, the valve relieves air
trapped between it and the air motor.
• Blow off button (BG): turns air on and off to push
the platen out of an empty drum.
• Safety Valve (BH): relieves air pressure if the air
motor pressure exceeds 60 psi (0.4 MPa, 4 bar).
• Safety Valve (BJ): relieves air pressure if the inlet
air pressure exceeds 100 psi (0.7 MPa, 7 bar).
