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 water delivery device that includes a body having a cold water inlet, a hot water inlet, and an outlet; a mixing valve in the body, and a touchscreen user interface on a surface of the body. The mixing valve includes a housing having a mixing chamber that is fluidly connected to the outlet, a first flow control valve moveably disposed in the housing to control a cold water flow from the cold water inlet to the mixing chamber, and a second flow control valve moveably disposed in the housing to control a hot water flow from the hot water inlet to the mixing chamber. The touchscreen user interface allows a user to control a temperature and/or a flow rate of water from the outlet by controlling the first and second flow control valves.

A flushing tool for a perforated tubing in a production tubing string is described. The flushing tool includes a chamber that is sealed at a pressure at or below atmospheric pressure when the flushing tool is in its sealed configuration, the chamber arranged to receive wellbore fluids when the flushing tool is in its activated configuration. A port allows ingress of wellbore fluids into the chamber when the flushing tool is in its activated configuration. A sealing means has a first position when the flushing tool is in its sealed configuration and a second position when the flushing tool is in its activated configuration. An actuator releases the flushing tool from its sealed configuration to its activated configuration by releasing the sealing means to move from the first position to the second position.

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 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.

A shower head that includes a movable handset, a mixing valve, and an electric heater. The movable handset includes a stem configured to detachably engage a shower head dock, and a spray head coupled to the stem and configured to discharge water. The mixing valve is disposed within the movable handset and includes a housing including a waterway located therein for water to flow through, a first flow control valve located within the housing and configured to control the flow of hot water to the spray head, and a second flow control valve located within the housing and configured to control the flow of cold water to the spray head. The electric heater is disposed within the movable handset and configured to heat at least part of the housing to an elevated temperature sufficient to kill organisms within the waterway.

The invention provides a passive fluidics circuit for directing different fluids to a common volume, such as a reaction chamber or flow cell, without intermixing or cross contamination. The direction and rate of flow through junctions, nodes and passages of the fluidics circuit are controlled by the states of upstream valves (e.g. opened or closed), differential fluid pressures at circuit inlets or upstream reservoirs, flow path resistances, and the like. Free diffusion or leakage of fluids from unselected inlets into the common outlet or other inlets at junctions or nodes is prevented by the flow of the selected inlet fluid, a portion of which sweeps by the inlets of unselected fluids and exits the fluidics circuit by waste ports, thereby creating a barrier against undesired intermixing with the outlet flow through leakage or diffusion.

A shower head having a stem, a spray head coupled to the stem and including a plurality of outlets for discharging water into at least one spray pattern, and a mixing valve located within the stem. The mixing valve has a housing having a first inlet, a second inlet and an outlet; a first flow control valve for controlling the flow of a first fluid from the first inlet to the outlet; and a second flow control valve for controlling the flow of a second fluid from the second inlet to the outlet. The shower head also has a touchscreen user interface located on a surface of the shower head, wherein the touchscreen user interface allows a user to control at least one of a temperature or a flow rate of fluid from the outlet to the spray head by controlling the first and second flow control valves.

A detergent dosing controller that is convenient to use and has better effect is disclosed herein. One side of the main passage is a water inlet (101), another side of the main passage is outlet (102) connecting to liquid inlet of washing bucket, and valves A(2), B(3), C(4), D(5), pump (6) and nozzle (7) are equipped. The inlet of valve A connects to the bypass orifice A(a) of the main passage, inlet of valve B connects to liquid storage tank of detergent A, outlets of valve A and valve B connect to inlet of valve C, inlet of valve D connects to liquid storage tank of detergent B, outlets of valve C and valve D connect to inlet of the pump, outlet of the pump connects to bypass orifice B(b) of the main passage, and for the relative location of bypass orifices A and B of main passage, bypass orifice A is relatively close to the inlet of main passage, bypass orifice B is relatively close to the outlet of main passage, the nozzle connects to main passage by concatenation and between bypass orifices A and B. The invention is applicable to the dosing of detergent for electric washing equipments.

A shower head that includes a stem, a spray head coupled to the stem and including a plurality of outlets for discharging water into at least one spray pattern, and a valve provided within one of the stem and the spray head.
