Valve Maintenance: 10 Considerations for Pressure Management Zones, DMAs

The Top 10 Valve Considerations for Pressure Management Zones and DMAs

By Brad Clarke

For basic pressure management or more advanced modulating pressure management, water suppliers create a network of District Metered Areas (DMA’s) or smaller, more manageable pressure zones. The DMA or pressure zone gives the ability to measure flow and control pressure, when a Pressure Reducing Valve (PRV) or Automatic Control Valve (ACV) is installed at the takeoff of the DMA from the Main Distribution line. Here are the top 10 considerations when choosing the correct valves to optimize the functionality and performance of the DMA.
