Inline Check Valve Code 1431

The Conflow Code 1431 - Inline Check Valves permit movement of flow media in one direction only. A light spring is fitted to assist valve closure at low pressure differentials across the valve. The valve, being in-line, fits compactly into a pipe line with minimum obstruction. May be used horizontally or vertically. For use with oil, water and air.

Typical Applications

  • On water dust suppression systems on mineral cutting machines to keep the pipelines "charged" with water so that the spray heads energise instantaneously when the supply valve is next turned on.
