Abstract
A core removably fits into an open cavity with an outer casing. The walls of the cavity and the core define an upstream manifold, a downstream manifold, and a planar manifold separating partition that lies at an acute angle to a flow plane aligned with the inlet to the upstream manifold and the outlet from the downstream manifold. A plurality of individually actuatable bistable valve elements are individually mounted onto the core without threaded bore connections in a parallel arrangement to connect the upstream and downstream manifolds across the partition. Preferably, the bistable valve elements each have a double cage between which a plug is guided from an open position to a closed position.
