A faucet that includes a housing, a first valve, a handle body, a handle, and a second valve. The first valve is disposed at least in part within the housing and controls one of a flow rate and a temperature. The handle body has an elongated base, which extends from the housing along a longitudinal axis and is operatively coupled to the first valve, such that rotation of handle body about the longitudinal axis relative to the housing controls the first valve. The handle extends from the base along a radial axis relative to the longitudinal axis. The second valve is disposed at least in part within the handle and controls the other of the flow rate and the temperature, the second valve operatively couples the handle to the base, such that rotation of the handle about the radial axis relative to the handle body controls the second valve.

A channel chip having a channel for running a fluid that is opened and closed by sliding on a film a sliding member slidable on the film while contacting with the film, the channel chip comprising: a substrate including a first channel, a second channel and a partition wall formed between the first channel and the second channel; a film including a diaphragm having a substantially spherical crown shape, the film being disposed on the substrate so that the diaphragm faces the partition wall; and a positioning section for holding the sliding member in such a way that the sliding member is slidable on the film while the positioning section positions the sliding member, the positioning section being disposed on the film.

This fluid handling device has a substrate, a film, and a sliding member. The substrate has first flow paths, second flow paths, and partition walls formed between one end of the first flow paths and one end of the second flow paths. The film includes a diaphragm, and is arranged above the substrate such that the diaphragm and the partition walls oppose one another. The sliding member has protrusions formed on the back surface thereof, and is arranged above the film with the back surface facing the film. By sliding on the film the sliding member is able switch alternately between a first state in which the protrusions are arranged so as not to oppose the partition walls, and the diaphragm is sandwiched therebetween, and a second state in which the protrusions are arranged opposing the partition walls, and the diaphragm is sandwiched therebetween.

An aspect includes a globe butterfly valve that includes a valve inlet, a valve outlet, a globe housing with a spherical body between the valve inlet and the valve outlet, and a globe butterfly valve disc operably disposed within the globe housing. The globe housing has a larger interior diameter than an inlet diameter of the valve inlet and an outlet diameter of the valve outlet. The globe butterfly valve disc is configured to block a flow path between the valve inlet and the valve outlet responsive to an outer edge of the globe butterfly valve disc being positioned proximate to an interior surface of the globe housing between the valve inlet and the valve outlet.

A device for mixing and metering of at least two gases, comprising two bodies that can be displaced relative to each other, wherein margins of the bodies are in contact with one another and between these margins at least two rectangular openings for one gas each can be formed, wherein a displacement of the bodies relative to each other automatically causes an increase of one opening and a decrease of the other opening, wherein the resulting total cross-section of the openings remains constantly the same here. Moreover, the device comprises a control element which is arranged adjacent to the two bodies and in contact therewith, wherein the control element can be translationally displaced in a continuous manner between a closed position and an open position in order to close or to open the openings.

A fluid handling system is provided that includes a controller, a plurality of valves, a pump, and an interface in communication with the controller. The valves can be operatively connected with a conduit to along a flow path. Each of the valves is controlled by the controller for selective movement between a first position and a second position. The first position closes the flow path, while the second position opens the flow path. The pump can be operatively connected with the conduit and the is controlled by the controller for selective pumping of fluid through the flow path. The interface allows selective definition of the flow path through the valves.

A plumbing component includes a valve provided within a portion of the plumbing component and configured to control the flow of water through the plumbing component. The valve includes a body and at least one waterway within the body. An electric heater extends through at least a portion of the body of the valve and is configured to heat at least a portion of the body to an elevated temperature sufficient to kill organisms within the waterway.

An aspect includes a globe butterfly valve that includes a valve inlet, a valve outlet, a globe housing with a spherical body between the valve inlet and the valve outlet, and a globe butterfly valve disc operably disposed within the globe housing. The globe housing has a larger interior diameter than an inlet diameter of the valve inlet and an outlet diameter of the valve outlet. The globe butterfly valve disc is configured to block a flow path between the valve inlet and the valve outlet responsive to an outer edge of the globe butterfly valve disc being positioned proximate to an interior surface of the globe housing between the valve inlet and the valve outlet.

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.
