A system for providing pneumatic power to a vitrector includes first (A) and second (B) output ports, an output valve (210), an isolation valve, and three manifolds. The first and second output ports provide pressurized gas to power a vitrector. The output valve alternately provides pressurized gas to the first and second output ports. The isolation valve (205) provides pressurized gas to the output valve. Two manifolds fluidly connect the output valve to the first and second output ports. A third manifold (255) fluidly connects the isolation valve to the output valve. When the isolation valve provides pressurized gas to the output valve, the output valve operates at a high rate of speed to alternately provide pressurized gas to the first and second output ports thereby powering the vitrector.
