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. The valve has a body including a waterway located therein for water to flow through, and a flow control valve located within the body and configured to control the flow of water to the plurality of outlets. The shower head also includes an electric heater extending through at least a portion of the body of the valve and configured to heat at least a portion of the body to an elevated temperature sufficient to kill organisms within the waterway.

Plumbing fixture with mixing valve and controller

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.

Thermostatic valve with anti-failure provisions

Embodiments include eyewash valves in which the temperature of the water emerging from the valve is thermostatically controlled by a wax motor which regulates the flow of hot and cold water through the valve. Embodiments include provisions for continuing water flow through the valve despite failure of the hot water supply. Embodiments also include provisions for water flow through the valve despite failure of the wax motor in the upper position or in the lower position.

Mixing valve

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.

Thermostatic mixing valve with integrated flow diverter

The invention relates to a thermostatic mixing valve with integrated flow diverter provided with a first coupling for a control lever for the flow rate adjustment and the flow diversion through a valve group that is housed between a base and a cylindrical body, and with a second coupling for a knob for the temperature adjustment through a thermostatic device, said valve including a member for the transmission of the flow rate adjustment and flow diversion control that directly connects the control lever to the valve group passing through the cylindrical body without moving it, the latter being also enclosed within an external casing secured to the base and achieving a watertight sealing with the base.

Flow control valve

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.

Valve disinfecting method

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.

Method of supplying temperature control fluid to temperature control system and storage medium

A temperature control system 1 includes a joint path 71 that supplies a fluid from a low-temperature path 76 having a variable valve 79 a and a high-temperature path 77 having a variable valve 79 c to a temperature regulation member 70 ; a bypass path 73 that has a variable valve 79 b 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 79 a and 79 b are opened to supply the fluid, and the valves 79 b and 79 c are opened to supply the fluid after detecting that the amount of the fluid in the tank 78 reaches the preset amount.
