Application and general characteristics :
- This valve controls and maintains a preset reduced downstream pressure regardless of variattions in demand and upstream pressure (the setting of downstream pressure is always below the upstream pressure)
- This valve reduces the pressure in network of water distribution, irrigation or pump outlet
Working Principle :
When the pilot M opens, pressure in the upper chamber is released and the valve A opens, reproducing the movement of the pilot.
When the pilot M closes, pressure in the upper chamber rises also and forces the membrane to close the main valve A which reproduces the movement of the pilot.
