TYPICAL AIR CONTROLLERS
The hand valve (left) is a typical two-position air valve. Constant pressure must be
applied to the control knob for the lift to operate. The foot valve (right) is of a similar
design and constant pressure on the pedal is required for lift operation. The foot
valve is supplied with a protective cover that has been omitted for clarity.
