<p>An air pressure and flow regulating valve for pneumatic tool mainly includes a valve body, a pressure regulator and a flow regulator connected to one side and a top, respectively, of the valve body, and an air inlet connector provided at a bottom of the valve body. By rotating a first turning knob provided on the pressure regulator, a narrow passage is produced in the valve body between the air inlet connector and the flow regulator, so that a pressure of air supplied into the pneumatic tool via the flow regulator is controllable via the size of the narrow passage. By rotating a second turning knob mounted around the flow regulator to fully open, partially shield, or fully close an outer air passage hole provided on the flow regulator, speed and flow of air supplied into the pneumatic tool can be changed under control.</p> |
