This needle valve is suitable for
accurately controlled gas admission in the range 10-3 to
10-6mbar/2x10-3 – 8x10-7 Torr. It
is fitted with a 20 turn 'counting dial' control knob to allow
repeatable flow rates to be set when required. Linear actuation of
the needle within the orifice results in a high degree of control
with prolonged needle and orifice life. The FCV10K is suitable for
pipeline or panel mounting.
We recommend the use of an in-line
filter on the inlet side of the valve to prevent damage to the valve
by dust or grit.
