Maric Flow Control Valves are used by water authorities for various applications.

Applications include:
  • Maintaining mains pressure
  • Extending water meter life, to prevent unbilled water usage
  • Facilitating distribution of water over vast distances
  • Reducing infrastructure costs
  • Restricting supply to prompt payment of overdue bills
  • Maximise revenue via optimised use of existing infrastructure

The Maric Flow Control valve is designed to deliver a fixed, pre-set, constant (maximum) flow of water – irrespective of pressure differential across it within a given range, typically 140-1000 kPa.

Usage by Water Authorities

Various water authorities have been installing Maric Flow Control valves as standard practice for many years – particularly for commercial connections, areas where unusually high pressure is supplied, and in areas where there is insufficient infrastructure to give everyone an unlimited/unrestricted supply.

Our valves are generally installed immediately next to the water meter.

Limiting flow rate to consumers is becoming increasing popular due to the many benefits this provides. A better understanding of peak demands assists the authority to ensure that agreed pressures exist, at the negotiated flow rate.
This in turn, also assists the authority to supply more customers.

Smaller connections usually use Insert type valves, larger connections usually use Screwed or Wafer type valves for flange mounting.

What the Maric Valve does

The Maric Flow Control valve is designed to deliver a fixed, pre-set, constant (maximum) flow of water – irrespective of pressure differential across it within a given range, typically 140-1000 kPa.
This means constant flow rate, irrespective of fluctuating pressure upstream or downstream of the valve.

Benefits of Maric Flow Control valves:
  • Compact – as compared with conventional diaphragm valves
  • Tamper proof – as these valves provide a fixed flow rate, it prevents unauthorized adjustment
  • Automatic – the rubber’s orifice diameter responds automatically to pressure fluctuations
  • Maintenance free – no external actuations or wearing parts
  • Self cleaning
  • Life span of up to 20 years
