Bertfelt - Threaded Constant Flow Valves

BT-Maric constant flow valves provide a constant, pre-determined, nominal flow rate for water and similar media regardless of the pressure variations. BT-Maric constant flow valves are designed for pipes from 1/8″ up to 2″ and regulate flow rate from as low as 0,15 L/min up to 342 L/min.

Wide range of flow rates available for water and other media as low as 0,15 L/min up to 342 L/min.
Wide range of sizes ?″, ¼″, ?″, ½″, ¾″, 1″, 1¼″, 1½″, 2″ or higher if needed and threaded connections (FF, FM, MF, MM).
Simple, compact, reliable and characterized by a long life (up to 20 years).
High accuracy of flow control: With our standard control rubber types PRECISION, we achieve an accuracy level of +/- 10% of the nominal flow rate. PRECISION covers the pressure drop range of 1,4-10 bar. (Other pressure drop ranges are available).
Solutions available from 0,4 bar up to 20 bar.
A wide variety of materials available: , , , U-PVC, POM, PVD-F, Titanium, Duplex, PE …
100% mechanical solution: no additional power source needed.
Self-cleaning, self-regulating.
Maintenance free: no need for spare parts. Due to the valves unique design and lack of wearing components spare parts are not available.
The constant flow valves are primarily for water applications and these valves are particularly suitable for use on poor water quality, because the flow controlling element is a rubber material, and flexes under normal operation conditions. This greatly minimizes the risk of blockage and eliminates the build-up of scale.
Pre-set flow rate to avoid adjustment errors or unwanted system changes.
Customized solutions are available.
