Pressure Sustaining Control Valve Water Transmission & Distribution
  • Sizes DN 50 – DN 1200.
  • Pilot senses the upstream pressure through a connection to the valve inlet. The valve and pilot remain closed until the inlet pressure exceeds the pilot setting.
  • Under flowing conditions, the pilot reacts to small changes in pressure to control the valve position by modulating the pressure above the diaphragm.
  • Should the upstream pressure fall below the set-point, the valve will close or modulate to ensure that the set-point is maintained.
  • Ensures minimum upstream pressure for critical use
  • Easily adjustable pressure setting
  • Closes if inlet pressure drops below set-point
