Pneumatic valves, pneumatic apparatuses, and methods for controlling pneumatic flow

A pneumatic apparatus comprising:

• a pneumatic valve comprising:
• a valve body comprising a valve chamber having a longitudinal axis;
• an inlet port formed through the valve body non-parallel to the longitudinal axis;
• a tool port formed through the valve body non-parallel to the longitudinal axis;
• an accessory port formed through the valve body parallel to the longitudinal axis;
• and
• a valve plug situated in the valve chamber and movable along the longitudinal axis to selectively open and close a pneumatic flow between the inlet port, the accessory port, and the tool port in response to relative pressure between the valve chamber and the inlet port;
• a pneumatic tool coupled to the tool port of the pneumatic valve;
• and
• a pneumatic accessory coupled to the accessory port of the pneumatic valve.

A method for controlling a pneumatic flow to a pneumatic tool and a pneumatic accessory, the method comprising:

• providing a pneumatic valve comprising:
• a valve body comprising a valve chamber having a longitudinal axis;
• an inlet port formed through the valve body non-parallel to the longitudinal axis;
• a tool port formed through the valve body non-parallel to the longitudinal axis;
• an accessory port formed through the valve body parallel to the longitudinal axis;
• and
• a valve plug situated in the valve chamber;
• coupling the pneumatic tool to the tool port;
• coupling the pneumatic accessory to the accessory port;
• supplying the pneumatic flow to the inlet port;
• and
• moving the valve plug along the longitudinal axis to selectively open and close the pneumatic flow between the inlet port, the accessory port, and the tool port in response to relative pressure differential between the valve chamber and the inlet port.
