Typical performance of BT-Maric constant flow valves

BT-Maric Constant Flow Valves provide precise, pre-set and constant flow regulation, regardless of pressure fluctuations. The flow remains stable even under varying operating conditions.

A very high accuracy guaranteed

In typical applications, our valves guarantee high accuracy of +/- 10% of the nominal flow rate across the entire differential pressure range from 1.4 to 10 bar.

Precision – as standard

Precision control rubbers are supplied as standard. Precision rubbers offer the best flow rate accuracy and tolerate a wide range of chemical environments. This makes them suitable for most mains pressure, pumping, industrial, and water treatment applications.

Applications

BT-Maric Precision control rubber joint certified to WaterMark, AS4020 and ACS potable water standards

Water Quality Certified

Precision control rubbers complies with the WaterMark licence and AS4020 Potable Water requirement and ACS.
