Claim Text:
1. A mechanical pneumatic valve for a pneumatic gun, comprising: a body comprising a plurality of ports for communicating compressed gas, said plurality of ports comprising an exhaust port and an internal port; a contact surface surrounding the exhaust port; a face seal configured to abut against the contact surface of the exhaust port and seal the exhaust port when the mechanical pneumatic valve is in a non-actuated state; a contact surface surrounding the internal port; and a mechanically-actuated valve actuator configured to actuate the mechanical pneumatic valve when the mechanical pneumatic valve is operatively arranged in the pneumatic gun, wherein the valve actuator is configured to move the face seal away from the contact surface of the exhaust port to exhaust compressed gas through the exhaust port, without the face seal sliding along the contact surface of the exhaust port, and wherein the face seal is configured to seal against the contact surface of the internal port without sliding along the contact surface of the internal port when the valve is actuated.
