A pneumatic valve for controlling whether a fastener driving device will drive a fastener into a workpiece, the pneumatic valve comprising: a body portion constructed and arranged to move at least between a rest position and a first position and to move between the rest position and a second position, the second position being between the rest position and the first position, wherein the pneumatic valve is configured to communicate with a detector and a trigger valve of the fastener driving device, wherein when the trigger valve is actuated before the detector detects that a nose of the fastener driving device is positioned proximate to the workpiece and the body portion moves from the rest position to the second position, the pneumatic valve causes the fastener driving device to drive the fastener, and wherein when the trigger valve is actuated and the detector does not detect that the nose is positioned proximate to the workpiece and the body portion moves from the rest position to the first position, the fastener driving device does not drive the fastener.
