The present disclosure relates to the field of fluid process systems and discloses a manifold system for fluid delivery. The system comprises a first set of Solenoid Operated Valves (SOVs), a second set of SOVs, a plurality of isolating valves, at least one first shuttle valve, and at least one redundant shuttle valve. Each set of SOVs includes at least two SOVs arranged in parallel. The SOVs together form a series-parallel redundancy.

A food article defect removal apparatus includes a manifold that defines one or more chambers for holding pressurized fluid. First channels extend from a first side of the manifold into fluid communication with the chambers. Second channels extend from the first side of the manifold to a second side of the manifold.

The manifold can have an exterior wall that at least partially defines a first chamber and a second chamber, with an interior wall disposed between the first chamber and the second chamber. The interior wall can define the second channels. The valves can be included with a valve assembly, which includes a driver operably coupled with the valves. The valves can be pluggably coupled with the driver.
