Turn the actuator handwheel clockwise,
linear drive will move down towards
the valve spindle, couple linear drive to
valve spindle.
Turn the tubular down stop clockwise
into the actuator until it comes to a
mechanical stop. If the valve must close
onto its seat by “TORQUE ACTION”
then back off (anti-clockwise) the down
stop by one third of one turn
(equivalent to 1mm). Run the lock nut
down ontothe tubular down stop and
tighten with two spanners. There is no
“up stop” (open) on the linear drive
unit, the mechanical stop in the valve
will give this position. Refit the top
cover tube to the handwheel using
PTFE tape to seal the thread.
The linear drive unit is pre-packed with
grease type Rocol MTS 1000, use this
or an equivalent high temperaturebearing
grease.
A grease nipple is situated in the base
of the actuator to enable lubrication of
the lead screw. Periodically, depending
on usage and temperature, apply two
pumps of a grease gun.
