An injection molding apparatus includes a first nozzle having a first nozzle melt channel in fluid communication with a manifold melt channel, and a second nozzle having a second nozzle melt channel in fluid communication with the first nozzle melt channel. A nozzle link is provided between the first nozzle and the second nozzle and includes a nozzle link melt passage for fluidly coupling the first nozzle melt channel and the second nozzle melt channel. The second nozzle includes a plurality of outwardly extending melt passages in fluid communication with the second nozzle melt channel. The outwardly extending melt passages deliver melt to a plurality of mold cavities through a plurality of respective gate seals and mold gates. A shut-off valve is disposed within a bore in the second nozzle. The bore intersects with one of the outwardy extending melt passages. The shut-off valve includes a passage therethrough such that when the passage is aligned with the outwardly extending melt passage, the melt stream may flow through the shut-off valve, and when the passage is aligned substantially perpendicular to the outwardly extending melt passage, the melt stream is prevented from flowing past the shut off-valve.
