A valve assembly includes a first housing that defines an inlet and a fluid output chamber. A second housing is engaged to the first housing and a cover is engaged to the second housing. A valve member is positioned within the first housing. An actuator is positioned between the second housing and the cover and is attached to the valve member through an engagement located within the first housing. A flow rate sensor, as a component of the valve assembly, may be positioned downstream of the inlet and the fluid output chamber.

Valve assembly

A housing assembly for a manifold includes a first housing with an inlet and a plurality of outlets, a second housing, and a valve retainer engaged with the first and second housings. The valve retainer includes a retention plate defined between first and second surfaces, a plurality of slot walls extending from the first surface, and a protruding edge that extends from a flanged lip and surrounds the plurality of slot walls. The retention plate defines a plurality of slots corresponding to the plurality of slot walls. The first housing may define a groove that receives the protruding edge, and the second housing may include a rim that engages the flanged lip of the valve retainer. Valve housings including first and second mating structures separated by wall segments may be positioned in outlets of the first housing and corresponding slots of the valve retainer.

Fluid distribution manifold

A fluid distribution manifold may receive a first required flow rate for a first flow of fluid that flows to a fluid handling device or a reservoir. A first operation state may be determined for a first valve assembly that regulates the first flow, the manifold may operate the first valve assembly based on the first operation state, and a first position tracker may be incremented based on the first operation. Based on a value of a cycle tracker, the manifold may identify a second valve assembly in an operation cycle and access a second control input that includes a second required flow rate for a second flow of fluid regulated by the second valve assembly. The manifold may cause the second valve assembly to operate based on at least one of a second operation state and a change in the second actual flow rate resulting from the first operation.

Systems and methods for controlling fluid flow with a fluid distribution manifold

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.

Systems and methods for controlling operations of a fluid distribution system

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.

Systems and methods for controlling operations of multi-manifold fluid distribution systems

A manifold can determine a turnover scheme including a target turnover schedule of target turnover levels, based on an operation schedule and efficiency setting for a fluid distribution. Each target turnover level can correspond to a volume of fluid to be cycled through the fluid distribution system over a period of time. The manifold can operate respective valves and a supply device based on a target turnover level and determine a current turnover level from a flowrate detected by a flow sensor for at least one of the valves. The manifold can receive a current usage of the fluid distribution system and determine a required turnover level. An override status for the turnover scheme can be based on the efficiency setting and a comparison of the current, target, and the required turnover levels, and the manifold can operate respective valves and the supply device based on the override status.

Systems and methods for turning over fluid distribution systems

A manifold includes a housing defining first and second inlets and outlets. With the housing, a valve retainer defines a first chamber in fluid communication with the first and second inlets. The valve retainer may engage a first valve assembly having a first actuator attached to a first valve member for regulating flow from the first outlet, and a second valve assembly having a second actuator attached to a second valve member for regulating flow from the second outlet port. A sensor assembly is configured to detect first and second operations of the first and second valve assemblies. A controller directs independent operations of the first and second actuators based on first and second flow rates derived from the first and second operations. The first and second valve members may be positioned within portions of respective first and second valve bodies in open fluid communication with the first chamber.
