If theValco ( VICI ) ElectricallyOper-
atedGasSamplingValve ( GSV ) in
your SRI 8610CGasChromatograph
does not operate, the problem can
sometimes be fixed by replacing the
circuit boards inside the valve actuator.
This is simpler and less expensive
than replacing the
entire actuator.
The board set is
SRI part#8670-0066-120volts or
#8670-0066-220volts
$295.00
Un-plug theGC from
mainspower
Remove the six screws holding the
bottom plate of theGC.
Tilt theGC on its back so you can see
