Functions:
• Limits the flow to within recommended operating limits regardless of upstream pressure variation.
• Reduces the pressure from the highest pressure upstream pipe to a steady lower downstream pressure regardless of variations in upstream pressure.
• Closes and restores distribution by manual control.
Sample applications:
• Limiting flow to a reservoir, treatment plant or bulk water supply to avoid peak flow demands and spread supply over time.
• Balancing flow in a network.
• Mixing water qualities.
• Reducing and stabilising downstream pressure to protect the supplied network when upstream pressure becomes excessive.
