Valve for Controlling a Flow of a Fluid

A valve for controlling a flow of a fluid comprises: a sealing plate comprising a plurality of ports for passage of the fluid through the sealing plate in a direction substantially perpendicular to the plane of the sealing plate; and a plurality of valve members, each valve member comprising at least one anchor portion arranged in fixed relationship with the sealing plate and a closure portion which is contiguous with the anchor portion and in movable relationship with the sealing plate under a differential pressure of the fluid across the valve, the closure portion being movable away from the sealing plate under a first differential pressure direction to open at least one of the ports and toward the sealing plate under a second and opposite differential pressure direction to close said at least one of the ports. The anchor portions of the plurality of valve members partition the closure portions from each other such as to define a plurality of valve cells, each valve cell comprising one of the valve members and at least one associated port.
