ABSTRACT:
An actuator valve for an air driven reciprocating device wherein the valve includes a control rod responsive to movement of the reciprocating device and a valve piston pneumatically actuated by movement of the control rod. The valve piston selectively directs air to reciprocate the driven mechanism. The control rod includes dual axial passageways to selectively vent each end of the cylinder within which the valve piston operates. The passageways are sealed such that unused pressurized air will not escape from the air valve.
