A mixing valve includes a mixing chamber, a first flow control valve having a first flow control opening, and a second flow control valve having a second flow control opening. The first and second flow control openings each have a diameter of approximately six millimeters and the mixing valve has a flow coefficient of approximately 2.5 when both flow control valves are in a mid-open position.

Fluid-dispensing systems and methods relating thereto are described. A method of dispensing fluid includes: (i) receiving, from a temperature encoder, a temperature signal; (ii) receiving, from a flow rate encoder, a flow rate signal; (iii) providing, based on the temperature signal and the flow rate signal, a first amount of power required by a first motor; (iv) providing, based on the temperature signal and the flow rate signal, a second amount of power required by a second motor; (v) opening, based on the first amount of power, the first valve by a first amount of valve opening; (vi) opening, based on the second amount of power, the second valve by a second amount of valve opening; and (vii) facilitating admixing of a first fluid flow at a first fluid flow rate, received from the first valve, and a second fluid flow at a second fluid flow rate, received from the second valve, to create an admixed fluid stream.

A multifunction tap assembly (18) for dispensing water, includes a tap body with a spout (2) for dispensing water. A valve body (6) has a mixer valve (8) including an inlet for water (20) from a hot water supply (H), an inlet for water (22) from a cold water supply (C), and an outlet. A selector control (14) on the valve body (6) can selectively direct cold water (30, 32) from the cold water supply to one or more water processing stations (34, 38). Each water processing station (34, 38) has an inlet for receiving cold water from the cold water supply as directed by the selector control (14) and processes the cold water to provide a processed water (36, 40) for dispensing from an outlet. A manifold connection (26) provides fluid communication between the outlet of the mixer valve (14) and each processing station outlet and has a manifold outlet in fluid communication with the spout (2).

A programmable sink valve system for controlling water flow into a sink is provided. The programmable sink valve system includes a housing including a main inlet and a main outlet, wherein the main inlet is connected to a water source; a valve assembly including a valve, wherein the valve assembly includes a valve inlet connected to the main inlet and a valve outlet connected to the main outlet; a flow sensor positioned on one of the valve assembly and the main outlet to monitor flow data; a controller connected to the valve of the valve assembly and the flow sensor; a timer configured to provide time data to the controller; and a memory. The controller receives the flow data from the flow sensor, receives the time data from the timer, and actuates the valve of the valve assembly in response to the flow data or the time data.

A remote fluid flow control system for controlling water flow to a faucet comprises a remote stand-alone foot pedal; and a main unit in wireless communication with the stand-alone foot pedal, wherein water flow to the faucet is controlled by the main unit in response.

An intelligent drainage device includes a power supply unit, a water discharge key, drain assemblies, a motor drive unit and a control unit. The drain assembly, installed to a bathtub drain hole, includes a waterstop member, a stepping motor and a receiving tube. The receiving tube engages fixedly and oppositely the waterstop member and a power transmission shaft of the stepping motor. The control unit receives a start/stop signal from the water discharge key, then transmits the signal to the motor drive unit for controlling the power transmission shaft to drive the corresponding waterstop member to move upward or downward. In this device, with a simple touch at the water discharge key, the control unit would control the motor drive unit to activate the stepping motors so as to have all the drain assemblies at the respective drain holes to discharge simultaneously and rapidly the water inside a bathtub.

An adjustment position of a water output device is provided. A flow volume adjustment component of the water output device has a first position corresponding to a flow volume greater than zero; upon detecting that the flow volume adjustment component reduces the flow volume to that corresponding to the first position, a detection component sends a signal to a control component; and the control component-turns off an electronic waterway switch according to the signal. In this way, when the flow volume is reduced, the electronic waterway switch can be turned off by signal control, and in this case, the flow volume adjusted by the flow volume adjustment component is kept at a particular value, such that the next time water is output by a user using an electronic mode, the failure of water output would not occur.

A control system for one or more ablutionary devices includes a mixer valve having a first inlet and a second inlet configured to receive a supply of hot and cold water, and an outlet configured to output cold water, hot water or a mixture thereof as an output stream for suppling water to the one or more ablutionary devices downstream of the mixer valve; and a controller. The controller is configured obtain one or more current operating signals related to the flow rate of the output stream produced by the mixer valve and compare each of the one or more current operating signals to a corresponding historical operating signal, the historical operating signal being an operating signal previously obtained by the controller, and to generate a diagnostic signal based on the comparison.

A control system for one or more ablutionary devices includes a valve having one or valve members each arranged to receive a respective water supply via one or more supply inlets, and an output for suppling output water to the one or more ablutionary devices downstream of the valve, the one or more valve members being arranged to control the flow of water between the one or more supply inlets and the output; one or more temperature sensors arranged to generate a respective temperature signal indicative of the temperature of any one or more of the water supply upstream of any one or more of the valve members, and the output water downstream of the one or more valve members; and a controller in communication with the one or more temperature sensors. The controller is configured to obtain one or more temperature signals from the one or more temperature sensors when the one or more ablutionary devices are not in use and to generate an indicator signal based on a comparison of the one or more temperature signals to one or more thresholds.

A control system for one or more ablutionary devices, comprising: a mixer valve having a first inlet and a second inlet configured to receive a supply of hot and cold water, and an outlet configured to output cold water, hot water or a mixture thereof as an output stream for suppling water to the one or more ablutionary devices downstream of the mixer valve; and a controller in communication with the mixer valve. The controller is configured to control the mixer valve according to one or more target output water properties; obtain one or more operating signals each related to an operating parameter of the control system; and generate, based on the one or more operating signals, a diagnostic signal that indicates an associated failure mode of the water supply if the mixer valve cannot be controlled to reach the one or more target water output properties.
