Maric flow control pressure sustaining valves automatically maintain a fixed, maximum constant flow rate – and are therefore often used to save water in homes, motels and commercial buildings in the following outlets:

  • Domestic showers, kitchen sinks, bathroom basins and laundry troughs – saving water in the home

  • Controlled flow – can also prevent scolding or freezing, when someone uses too much cold or hot water

  • Water hammer prevention

  • Drinking Fountains – controlled stream prevents frustration at the drinking fountain

  • Toilet Cisterns -prevents the potential “continuous flush” operation if fill rate is too fast

  • Water Heaters – keeping flow below a pre set maximum ensures gas & electric instantaneous heaters can heat to a sufficiently hot temperature

For most domestic applications, the use of Kwyflo type pressure sustaining valves is recommended for more quiet operation.

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
