ABSTRACT:
An air tool for setting fasteners includes a pressure selecting valve member and internal passages for air balancing this valve member with a pressure relief pilot valve for bleeding a chamber of the valve member to atmosphere responsive to increased motor operating pressure. A plurality of such pilot valves may be provided in a manually rotatable selector disc. Each pilot valve may be set to a different torque output for quick and easy tool adjustment upon registering a given pilot valve with the pressure selecting valve chamber upon manipulation of the selector disc.
