The pressure loss in a water supply network will change according to the variations in flow conditions. Pressure loss depends on friction, which is a function of flow rate and pipe length. Flow rates will be higher in a smaller pipe and will cause a higher pressure loss.
If there is no flow, there will be no pressure loss. The pressure in the pipe network will then be a static pressure supplied from the pump or reservoir, plus or minus the vertical difference between the point of supply and the point of pressure reading. If there is a flow, there will be a pressure loss depending on flow rate and pipe length. The pressure loss can be substantial in long supply pipelines.
AVK control valves are effective when it comes to minimising high pressure loss in the supply network; and keeping a more constant pressure will prevent leaks caused by unnecessary stress of the supply network due to pressure fluctuations.
AVK control valves are available in various configurations and can be used in many different applications. We have prepared some examples that you find below.
