Pressure Reducing Valves
The most commonly used device for regulating water flow in pipelines is the pressure reducing valve. These valves provide a mechanical constriction in the pipe, much as an orifice plate reduces the cross-sectional flow area, thereby effecting a local pressure drop in the flow. Pressure reducing valves need to be sized correctly in order for optimum control, then be used at the same flow rate and valve size to obtain the pressure loss. We have range of brass and plastic units from suppliers such as Netafim.
