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.

A valve arrangement including a valve and a valve actuation arrangement is provided. The valve has a known flow profile. The valve includes a valve member and a valve stem operably coupled to the valve member for adjusting the position of the valve member. The valve actuation arrangement is operably coupled to the valve stem. The valve actuation arrangement includes a drive arrangement and a control arrangement. The drive arrangement is operably coupled to the valve stem and configured to adjust an actual stem position of the valve stem based on an actual stem positional signal. The control arrangement is configured to generate the actual stem positional signal. The control arrangement is configured to generate the actual stem positional signal based on an input control signal representing a desired stem position based on a desired flow profile being different than the known flow profile.

The invention relates to a device for stimulating an udder during milking, made up of a housing with a first connection (350, 351) and a second connection (352, 353), which housing can be grasped by a hand. The first connection connects the housing to a pulsator and the second connection connects the housing to a teat cup. A throttle valve (305, 306) is interposed between the first connection and the second connection. A control device (309) is housed in the housing and is adapted to bring the throttle valve, after a defined duration, from a partially open to an open position.

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.

A shower head having a stem; a spray head coupled to the stem; a mixing valve located within the stem or the spray head, the mixing valve having a first valve member assembly for controlling a first fluid flow to a mixing chamber and a second valve member assembly for controlling a second fluid flow to the mixing chamber. Each valve member assembly includes a spool, a first valve member on the spool that engages with a first valve seat in a closed position and a second valve member on the spool that engages with a second, separate, valve seat in the closed position. An electrically powered first motor is located within the stem or the spray head. The first motor is coupled to the first valve member assembly to control movement of the first valve member assembly to control the flow of the first fluid to the mixing chamber.

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.

A mixing valve having a housing and first and second flow control valves. The housing has a mixing chamber, a first outlet, and a second outlet. The first flow control valve controls fluid flow through the first outlet to the mixing chamber, and the second flow control valve controls fluid flow through the second outlet to the mixing chamber. The first and second outlets each have a size so that the mixing valve has a flow coefficient of approximately 2.5 in a mid-open position of both flow control valves, and the housing has a length dimension, a width dimension, and a thickness dimension, and the largest of these dimensions is no more than approximately 65 millimeters.

A valve arrangement including a valve and a valve actuation arrangement is provided. The valve has a known flow profile. The valve includes a valve member and a valve stem operably coupled to the valve member for adjusting the position of the valve member. The valve actuation arrangement is operably coupled to the valve stem. The valve actuation arrangement includes a drive arrangement and a control arrangement. The drive arrangement is operably coupled to the valve stem and configured to adjust an actual stem position of the valve stem based on an actual stem positional signal. The control arrangement is configured to generate the actual stem positional signal. The control arrangement is configured to generate the actual stem positional signal based on an input control signal representing a desired stem position based on a desired flow profile being different than the known flow profile.

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.
