closed valve. lt is equipped
with a mechanical SPST
contact activated when the
flow velocity drops below
the factory preset value of
0.15 m/s (0.5 ft/s). The F3.05
features a LED which shows
the flow status locally.
A specially designed family of
fitting ensures an easy and
quick installation into all pipe
materials in sizes from DN15
to DN600 (0.5” to 24”).
