The disclosure is directed to a fault tolerant fluid flow apparatus which will continue to function during a malfunction of a valve utilized therein. The disclosed apparatus uses parallel arms, each containing serially connected valves and may be incorporated in a manifold. One embodiment utilizes an inlet and outlet switching valve so that one of the parallel arms can be closed off from fluid flow for service of a valve therein.

A fault tolerant parallel and serial fluid flow apparatus comprising: (a) an inlet and an outlet; (b) at least two parallel fluid flow arms, each said arm comprising at least two serially disposed valves, each said valve being capable of controlling fluid flow from full throughput of fluid flow at a fully open position to no fluid flow at a fully closed position; (c) means positioned between said inlet and said parallel fluid flow arms for selectively controlling fluid flow from said inlet to each of said arms, said inlet controlling means being capable of directing fluid flow from said inlet to both said parallel arms simultaneously and to each said arm individually, such that fluid flow to one said arm can be stopped for service of a valve therein.
