ABSTRACT:
This invention discloses a control valve comprising a plurality of circular cylindrical wall partitions separating a first compartment open to an inlet port from a second compartment open to an outlet port of the control valve, wherein each of the circular cylindrical wall partitions including a plurality of groups of holes disposed therethrough and arranged in an axially distributed pattern in groups is wrapped by the belt under tension provided by at least one idler roller disposed in an orbiting relationship about the central axis of the circular cylindrical wall partition, which belt covers up all of the groups of holes except one group when the idler roller is orbited to each of the predetermined positions about the circular cylindrical partitioning wall by a rotary actuator. A controller controlling the rotary actuators orbits the plurality of idlers respectively belonging to the plurality of individual control valves to different combinations of positions which provide different combinations of open holes disposed through the circular cylindrical wall partitions.
