  2. Pressure regulator - Wikipedia

    en.wikipedia.org/wiki/Pressure_regulator

    Pressure regulator for domestic water supply. Outlet pressure is set with the blue handwheel and shown on the vertical scale. A water pressure regulating valve limits inflow by dynamically changing the valve opening so that when less pressure is on the outside, the valve opens up fully, and too much pressure on the outside causes the valve to shut.

  3. Hydronic balancing - Wikipedia

    en.wikipedia.org/wiki/Hydronic_balancing

    Hydronic balancing, also called hydraulic balancing, is the process of optimizing the distribution of water in a building's hydronic heating or cooling system by equalizing the system pressure. In a balanced system every radiator is set to receive the proper amount of fluid in order to provide the intended indoor climate at optimum energy ...

    en.wikipedia.org/wiki/Reduced_pressure_zone_device

    A reduced pressure zone device (RPZD, RPZ, or RPZ valve) is a type of backflow prevention device used to protect water supplies from contamination. RPZDs may also be known as reduced pressure principle (RP), reduced pressure principle backflow prevention devices, [1] [2] reduced pressure zone assemblies (RPZA), [3] or reduced pressure principle ...

    en.wikipedia.org/wiki/Diatomaceous_earth_filtration

    Pressure filters find widespread application in municipal water systems, industrial settings, residential well water systems, and swimming pools. These DE filtration systems are rather simple and can be used in a vertical or horizontal setting and can be modified to allow the application of multimedia filters.

  7. 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.
