Pressure considerations for reservoir inlet control valves
/
Both pressure and flow velocity must be considered when designing reservoir level control systems.

Even water distribution in sprinkler systems
/In a recent Irrigation project in Mozambique, the designers needed to install a pressure-sustaining valve on the outlet of each hydrant to ensure even distribution of pressure and to prevent one area from taking all the flow and “starving” other areas.

/
Variations in the Total Dynamic Head (TDH) used in the selection of borehole pumps creates a situation where there is no single duty point but a range of duty points that move between a maximum and a minimum value.

/
Throttling pumps by using valves is a common practice in many plants. But it is far from an ideal practice, particularly because of the energy (and monetary) losses it involves.
