2. 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.

3. Tap (valve) - Wikipedia

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

   Water and gas taps have adjustable flow: gate valves are more progressive; ball valves more coarse, typically used in on-off applications. 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.

4. Delta Faucet Company - Wikipedia

   en.wikipedia.org/wiki/Delta_Faucet_Company

   Delta Faucet Company is a division owned by Masco, which was founded in Detroit in 1929 by Armenian immigrant Alex Manoogian. In 1952, an eager inventor brought Manoogian his latest invention, a one-handled faucet that mixed both hot and cold water with a ball-valve. Unfortunately it leaked, but Manoogian was intrigued by the idea of utilizing ...

5. Water hammer - Wikipedia

   en.wikipedia.org/wiki/Water_hammer

   Fit slowly closing valves. Toilet fill valves are available in a quiet fill type that closes quietly. Non-slam check valves do not rely on fluid flow to close and will do so before the water flow reaches significant velocity. High pipeline pressure rating (does not reduce the effect but protects against damage).

6. Valve leakage - Wikipedia

   en.wikipedia.org/wiki/Valve_leakage

   The importance of valve leakage depends on what the valve is controlling. For example, a dripping tap is less significant than a leak from a six-inch pipe carrying high-pressure radioactive steam. In the United States, the American National Standards Institute specifies six different leakage classes, with "leakage" defined in terms of the full ...

7. Bathtub curve - Wikipedia

   en.wikipedia.org/wiki/Bathtub_curve

   The bathtub curve is a particular shape of a failure rate graph. This graph is used in reliability engineering and deterioration modeling. The 'bathtub' refers to the shape of a line that curves up at both ends, similar in shape to a bathtub. The bathtub curve has 3 regions: The first region has a decreasing failure rate due to early failures.

8. Flow coefficient - Wikipedia

   en.wikipedia.org/wiki/Flow_coefficient

   A simplified version of the definition is: The k v factor of a valve indicates "The water flow in m 3 /h, at a pressure drop across the valve of 1 kgf/cm 2 when the valve is completely open. The complete definition also says that the flow medium must have a density of 1000 kg/m 3 and a kinematic viscosity of 10 −6 m 2 /s , e.g. water.

9. Pressure drop - Wikipedia

   en.wikipedia.org/wiki/Pressure_drop

   Pressure drop (often abbreviated as "dP" or "ΔP") [1] is defined as the difference in total pressure between two points of a fluid carrying network. A pressure drop occurs when frictional forces, caused by the resistance to flow, act on a fluid as it flows through a conduit (such as a channel, pipe, or tube).
