A liquid fuel injector (56) such as for a dual fuel system (34) in an internal combustion engine (10) includes two-way injection control valves (82,85) for controlling twin outlet checks (74,78). A first set of orifices (86) are arranged in an A-F-Z pattern, and a second set of orifices are arranged in an A-F-Z pattern, within the fuel injector (56), among a high-pressure inlet passage (60), a low-pressure space (72), and first and second outlet check control chambers (68,70), respectively. A common nozzle supply cavity (90) is fluidly connected to the high-pressure inlet passage (60) and supplies each of two sets of nozzle outlets (64,66) opened and closed by the twin outlet checks (74,78).
