  2. Thermostatic mixing valve - Wikipedia

    en.wikipedia.org/wiki/Thermostatic_mixing_valve

    These are single Outlet Thermostatic Mixing Valves, often called "thermostatic faucets", "thermostat taps" or "thermostat valves". Designed for single point applications, such as individual showering, hand wash basin mixers, bath or tub fillers; High level protection against scalding and thermal shock

  3. Tap (valve) - Wikipedia

    en.wikipedia.org/wiki/Tap_(valve)

    Turning a valve knob or lever adjusts flow by varying the aperture of the control device in the valve assembly. The result when opened in any degree is a choked flow . Its rate is independent of the viscosity or temperature of the fluid or gas in the pipe, and depends only weakly on the supply pressure , so that flow rate is stable at a given ...

  9. Pressure-balanced valve - Wikipedia

    en.wikipedia.org/wiki/Pressure-balanced_valve

    The pressure-balanced shower valve compensates for changes in water pressure. It has a diaphragm or piston inside that reacts to relative changes in either hot or cold water pressure to maintain balanced pressure. As water pressure drops on one supply line, the valve reduces the pressure in the other supply line to match.
