Abstract: A faucet that includes a base, a spout, a valve body, a first flow control valve, a second flow control valve, and an electric heater. The valve body includes a first end section, a second end section having an outlet, and a center section provided between the end sections and including first and second inlets configured to receive cold and hot water, respectively. The first flow control valve is located within a first waterway of the valve body to control the flow of cold water, and the second flow control valve is located within a second waterway of the valve body to control the flow of hot water. The electric heater extends through the valve body and is configured to heat a surface defining at least a part of one of the first and second waterways of the valve body to an elevated temperature sufficient to kill organisms therein.

Abstract: A control system includes a water delivery device and a communications bridge. The water delivery device includes a mixing valve, a controller configured to control the mixing valve, and a first optical communications interface coupled to the controller. The communications bridge includes a second optical communications interface and a separate data communications interface. The communications bridge is configured to exchange information with the water delivery device using optical communications via the first and second optical communications interfaces, and to exchange information with a user device using electronic data communications between the user via and the data communications interface.

Abstract: A valve including a housing having a first inlet chamber defined by a first chamber wall and configured to receive the cold water, a second inlet chamber defined by a second chamber wall and configured to receive the hot water, and a mixing chamber configured to receive the cold water from the first inlet chamber and the hot water from the second inlet chamber, wherein at least a portion of the mixing chamber is located between the first and second chamber walls; a first flow control valve extending through the first inlet chamber and moveable relative to the housing for controlling the flow of cold water from the first inlet chamber to the mixing chamber; and a second flow control valve extending through the second inlet chamber and moveable relative to the housing for controlling the flow of hot water from the second inlet chamber to the mixing chamber.

Abstract: A showerhead that is configured to receive a supply of cold water and a supply of hot water. The showerhead includes a body, a mixing valve within the body that includes a first actuator within the mixing valve for controlling a first flow control valve within the mixing valve and a second actuator within the mixing valve for controlling a second flow control valve within the mixing valve, and a controller on or within the body that is configured to send a control signal to control actuation of the first actuator and the second actuator.

Abstract: 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.

Abstract: A water delivery device includes a body, a user interface, a micro-mixing valve, first and second capacitive sensors, and a controller. The body includes a base and a spout. The user interface is provided on the spout. The micro-mixing valve is contained within the body and is in fluid communication with a hot water source and a cold water source. The first capacitive sensor is provided below the user interface. The second capacitive sensor is provided below the user interface and is spaced apart from the first capacitive sensor. The controller is operatively connected to the first capacitive sensor, the second capacitive sensor, and the micro-mixing valve. Each of the first and second capacitive sensors is configured to be independently activated by a user to transmit a signal to the controller to increase or decrease a temperature of a flow of water flowing from the micro-mixing valve.

Abstract: A plumbing fixture having a body and a mixing valve provided within and separate from the body. The mixing valve has a housing that is separable from and disposed within the body, wherein the housing includes a mixing chamber for receiving cold water, hot water or a mixture thereof; a first flow control valve for controlling a flow of cold water to the mixing chamber; and a second flow control valve for controlling a flow of hot water to the mixing chamber. Each flow control valve has a first valve member, which is configured to engage with a valve seat of the housing in a closed position, and a second valve member, which is configured to engage with a separate valve seat of the housing in the closed position. A portion of the mixing chamber in the housing is located between the first and second flow control valves.
