Hydraulic / Electronic Pressure Reduction Valves For Pressure Management Applications
Water companies and authorities are committed to the uninterrupted supply of water at the required quantity, quality, and pressure. In Israel, as in the rest of the Western world, water system planning is based on the assumption of growth in both population and demand, with the objective being the system’s ability to cope with peak demand days and hours, for the duration of the system’s expected lifespan.
In many instances, the water supply system is adjusted to the daily peak demand hours. Pressure reducers, for example, are calibrated to maintain a consistent pressure at the pressure reduction point, such that it will be sufficient to cope with demand during peak hours. In these cases, there are many periods of operation during which the system is working in a state of over-production, with excess pressure in the system.
Dynamic pressure control that adjusts to changing conditions throughout the day and from season to season, is an efficient tool that contributes greatly to several aspects of the system’s operation.
