Procedure
– Insert plug stem (5) into the valve as far as it
will go.
– Move actuator stem (1) to mid-position (see
"4.4 Manual operation").
– Place actuator (8) on the valve bonnet and
secure with ring nut (7) (allow to fall over the
stem when placing).
– Push plug stem (5) up, connect coupling nut
(3) and actuator stem (1) via the coupling
halves (2) and tighten with screws.
– Move actuator stem (1) to the final position
by turning the handwheel clockwise.
– Align travel indicator scale (6) with the tip of
the coupling (2) and screw tight.
– Tighten the plug stem (5) with the lock nut
(4) against the coupling nut (3).
CAUTION!
!
Do not press valve plug or final control
element onto the seat and turn.
This could cause the final control ele-
ment and the actuator to be damaged.
The linear actuator can be attached similarly
to other final control elements, e. g. butterfly
valves with attached pedestal.
