About Maric Flow Control
Precision Flow. No Matter the Pressure.
Maric Flow Control is an Australian engineering firm specializing in constant flow valves that regulate liquid flow rates across wide pressure variations. With over 50 years of manufacturing expertise, Maric has become a globally trusted name for non-powered, maintenance-free flow regulation. The company’s patented valve design features a precision-molded rubber control ring that automatically adjusts its orifice based on pressure differential, ensuring accurate and consistent flow regardless of input conditions.
Maric valves are renowned for their compact design, long operational life, and compatibility with a wide range of piping systems and fluids. Their products are ideal for industries requiring precise flow control, water conservation, and equipment protection—especially where pressure conditions are variable or unstable.
The Maric flow control valve is designed to deliver your required flow rate, irrespective of pressure differential*, over a wide range**.
The minimum differential required to achieve rated flow for a Precision Maric valve is 140 kPa.
WHY USE MARIC VALVES?
- Valuable protection for flow rate sensitive pumps, filters, pump glands, and water distribution systems.
- The valves boast automatic, maintenance free, and self cleaning operation.
- The valves useful life can be up to 20 years.
- They are compact and are available in the broadest range of connection types, sizes and material types in the world.
*Pressure differential is difference between the inlet and outlet pressure
**Pressure differential range for Precision type Maric valves is 140 – 1000 kPa
