WebThe spillback valve recycles discharge gas back to the suction to control throughput. Throughput can also be controlled incrementally with clearance pockets that allow the operator to set the capacity at various points, such as zero, 50, 90, and 100%. The board operator can change the capacity up or down via load and unload buttons.
