A first valve of a manifold for a fluid distribution system may regulate a fluid flow to a first fluid handling device (“FHD”). A second valve of the manifold may communicate with a second FHD, a reservoir, or a recirculation line. A target flow condition for the manifold may be determined by a manifold control system (“MCS”) based on a device setting received for the first FHD. The MCS may determine a fluid distribution system operation for obtaining the target flow condition based on the target flow condition, a flowrate of the fluid flow, and an operational state of a supply device. The operation may include the MCS controlling at least one of the supply device, the first valve, and the second valve to change the flowrate. The MCS may continuously operate at least one manifold valve to maintain the target flow condition once exhibited by the manifold.

A system and method for controlling operations of a fluid distribution may include a first manifold receiving a next mode of operation for the fluid distribution system. The first manifold may calculate first and second flow requirements for the first and second manifolds that may respectively include a first and second total flowrates from the first and second manifolds. The first manifold may determine required operation states for valves of the first manifold and the second manifold for the next mode based on the first and second flow requirements. The first manifold may be controllably operated to cause the second manifold and a supply device of the fluid distribution system to operate in the required operation states and provide first and second flow requirements. The first manifold may direct the second manifold to independently balance individual outlet flowrates of the second manifold while continuing to provide the second flow requirements.
