Maric Flow Control Valves

Maric Flow Control valves maintain a fixed, pre-set, constant flow rate, regardless of pressure.

A constant flow rate, even while demand for water, or upstream or downstream pressures are changing, can offer valuable protection for flow rate sensitive equipment and water distribution systems. Read More

Why use a Maric Flow Control Valve?Maric Flow Control Valves

  • Valuable protection for flow rate sensitive pumps, filters, pump glands, and water distribution systems.
  • 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

Maric Flow Control is an Australian owned manufacturing engineering firm situated in Adelaide, South Australia.
