Applications
FG-3 models are for general use in
meter-in, meter-out or bleed-off
applications.
FCG-3-***-*-10 models are for general use
in meter-in or meter-out applications in
which high reverse flow rates can occur.
FCG-3-***-A-10 models are for similar
use in those meter-in applications where
the possibility of transient surges above
the controlled flow rate setting,
whenever flow is first directed to the inlet
port, is undesirable, e.g.
– for feed speed control
– for successive fast approach/feed
sequences (fine machining of
interrupted bores).
