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.

A flow control valve includes a valve inlet configured to receive a fluid, a valve outlet configured to output the fluid, and a valve member assembly for controlling the fluid flow through the flow control valve. The valve member assembly and the valve inlet are configured such that, when in use, fluid flowing through the flow control valve exerts substantially no net force on the valve member assembly.

A method of performing a cleaning cycle for a water supply system having a valve. The method includes determining whether the cleaning cycle is necessary in a central controller located remotely from the water supply system; and when cleaning is necessary, sending a signal from the central controller to a local controller located within the water supply system to activate a heating element within the water supply system to heat an internal waterway of the water supply system to a temperature configured to clean the internal waterway.

A plumbing fitting having a body and a housing located in the body that includes a first inlet for receiving the first fluid, a second inlet for receiving the second fluid, and a mixing chamber. The plumbing fitting includes a first flow control valve operatively coupled to the housing; a second flow control valve operatively coupled to the housing; and an actuator assembly configured to move the first flow control valve relative to the housing to control flow of the first fluid from the first inlet to the mixing chamber, such that the first fluid exerts substantially no net force on the first flow control valve, and configured to move the second flow control valve relative to the housing to control flow of the second fluid from the second inlet to the mixing chamber, such that the second fluid exerts substantially no net force on the second flow control valve.

A temperature control system 1 includes a joint path 71 that supplies a fluid from a low-temperature path 76 having a variable valve 79a and a high-temperature path 77 having a variable valve 79c to a temperature regulation member 70; a bypass path 73 that has a variable valve 79b and circulates the fluid flowing a collection path 72 that collects the supplied fluid through the temperature regulation member; a circulation pump 87 at the collection path; and a tank 78 that is provided at an upstream side of the circulation pump and supplies the fluid to the circulation pump when an amount of the fluid reaches a preset amount. The variable valves 79a and 79b are opened to supply the fluid, and the valves 79b and 79c are opened to supply the fluid after detecting that the amount of the fluid in the tank 78 reaches the preset amount.

A mixing valve includes a first inlet for receiving a first fluid, a second inlet for receiving a second fluid, and a mixing chamber having a fluid outlet for outputting the first fluid or the second fluid or a mixture thereof. The mixing valve includes a first flow control valve for controlling the flow of the first fluid into the mixing chamber and a second flow control valve, separate from the first flow control valve, for controlling the flow of the second fluid into the mixing chamber. At least one of the first or second flow control valve includes at least two separate outlets into the mixing chamber.

A mixing valve includes an inlet and a flow control valve that includes a valve member assembly having a first valve member coupled to a second valve member. The first and second valve members are spaced apart from each other and are configured to seal two separate outlets when the flow control valve is in a closed position. The mixing valve also includes a stepper motor configured to simultaneously move the first and second valve members to selectively seal or unseal the two separate outlets.

Apparatus and method for determining endpoint of a fluid supply vessel in which fluid flow is controlled through a flow passage disposed in an interior volume of the fluid supply vessel with a static flow restricting device and a selectively actuatable valve element upon establishing fluid flow. The endpoint determination can be employed to terminate fluid supply from the fluid supply vessel and/or to switch from a fluid-depleted supply vessel to a fresh vessel for continuity or renewal of fluid supply operation. The apparatus and method are suitable for use with fluid-utilizing apparatus such as ion implanters.

A faucet assembly including a handle that rotates about a rotational axis extending perpendicular to an angled interface for adjusting a water parameter.

A kitchen faucet is provided that automatically fills a vessel up to a user-specified level without regard to a specific volume. The faucet illustratively includes a faucet body and a spray head that can be detached from the faucet body, such as a pull-down or pull-out faucet. The faucet illustratively includes a user interface for setting the level at which to fill the vessel (e.g., 20%, 40%, 75%, etc.). The spray head illustratively includes sensor(s) to determine a water level in the vessel in relation to its top edge. This allows a vessel to be filled to a user-specified level regardless of the vessel shape or size.
