Many unique features for BT-Maric constant flow valves:

BT-Maric control valves maintain a fixed, pre-set, constant flow rate, regardless of pressure. You will find below a list of many unique features for BT-Maric constant flow valves:

A wide and complete range of BT-Maric constant flow valves

A wide and complete range of BT-Maric constant flow valves

  • Designed for flow rates starting as low as 0.15 L/min going up to 13 500 L/min.
  • Flow rates available in incremental small steps.
  • 100% mechanical, self-regulating and does not require additional energy.
  • Extremely precise: Our standard solution Precision has an accuracy of nominal flow rate +/- 10%, for the whole pressure drop range starting as low as 1,4 Bar up to 10 Bar.
  • Simple, compact, reliable and characterized by a long operating life (20 years).
  • Wide range of connection types and materials are available.
  • High Pressure solutions managing pressure differentials up to 20 Bar.
  • Low Pressure solutions managing pressure differentials from 0,4 Bar.
  • Maintenance free: no need for spare parts. Due to the valves unique design and lack of wearing components spare parts are not available.
  • Pre-set to avoid adjustment errors or unwanted system changes => the flow rate must be specified when ordering.
  • Significantly reduce investment and operating costs.
  • Prevent equipment break-down and extend life span of your equipment/product. 
  • A constant flow rate can offer valuable protection for sensitive equipment and water distribution systems
  • Self-regulating: the rubber’s orifice diameter responds automatically to pressure fluctuations.
  • Self-cleaning: do not clog.
  • The constant flow valves are primarly for water applications and these valves are particularly suitable for use on poor water quality because the flow controlling element is a rubber material which flexes under normal operation. This greatly minimizes the risk of blockage and thus eliminates the build-up of scale.
  • Save water or other media. Reduce waste. 
  • Conform to industry standards and quality: ISO9001:2015, ISO140001:2015 and French certificate of sanitary conformity (ACS).as well the Australian potable water authority.
  • We help our customers to customise valves and inserts.
