BERMAD 7PM Operation

Watch this video to learn more about the operation of the BERMAD 7PM Pressure Management Valve, a flow compensated pressure reducing valve.

Pressure Managament Normally Open Valve

This animation describes the typical behavior of pressure versus flow in residential type neighborhoods, the leakage & pipe burst problems caused by excessive pressure that results in revenue loss for the water supply company and even leads to pipe bursts at the distribution lines.

Pressure Management Valve Model 7PM

The model 7PM Flow Compensated Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve that automatically and continuously optimizes downstream pressure, correlating valve setting with demand.

  • Self contained hydro-mechanical
    • Does not rely on electrical power supply
    • Does not require additional pipeline accessories
  • Universal fitting
    • Applicable to all sizes
    • Easily retro-fitted
    • Low maintenance and installation costs
  • Simple design
    • Does not require specialist commissioning
    • Fits all “sites”
  • Double chamber design
    • Moderated valve reaction
    • Protected diaphragm
  • V-Port throttling plug
    • Very stable at low flow
    • Increased valve travel
  • Obstacle free, full bore – Free flow pass
  • In-line serviceable – Easy maintenance

Typical Applications

A well-planned pressure management program can significantly reduce not only volumes of real loss, but also maintenance costs by reducing occurrence of bursts and thereby extending the life of the system.The Flow Compensated Pressure Reducing Valve, Bermad Model 7PM is designed to automatically and continuously optimise downstream pressure, correlating valve setting with demand. As a result, the average network pressure dramatically decreases, reducing system leakage, bursts, maintenance and energy costs. The shaded area represents the hours and levels of reduced leakage.
