An ejector for an objector product sorter is disclosed which, in one embodiment, has a solenoid with a coil having a hollow center through which air flows and, in one aspect, has a relatively small air reservoir space to increase ejector accuracy. In one embodiment, balanced air flow provides for uniform travel of a valve seat cover, further increasing accuracy and efficiency.
