Maric Flow Control Valve

Maric Flow Control Australia is an Australian owned engineering firm situated in Adelaide, South Australia. Established in 1963, the company manufactures the Maric flow control valves, and exports around 50% of its production through overseas distributors.

Maric flow control valves maintain a constant pre-set flow rate of water, over a wide pressure range. For flow rate sensitive pumps, filters, pump glands and water distribution systems, the installation of these valves can offer many benefits and valuable protection. The technology is based on a precision moulded rubber control ring in the valves’ body, with an orifice diameter that varies in response to the pressure differential applied to it. The greater the pressure, the smaller the orifice, and vice versa, thereby maintaining a constant flow.

The high quality of all Maric valves is maintained through the use of a quality assurance program based on ISO9001 and is audited by SAI Global, (a division of Standards Australia). This allows the company to be both quality assured and hold a current WaterMark License.

The valves are reliable, compact, self-cleaning and are maintenance-free throughout the life of the valve. Flow rate increases generally one half to one percent per year. Therefore depending on the accuracy required by the installation, valve life can be up to 20 years.
