Specifications
Refer to table 1 for 1008 handwheel actuator
specifications. Refer to the actuator nameplate for
information about a specific actuator.
Installation
WARNING
Always wear protective gloves,
clothing, and eyewear when
performing any installation operations
to avoid personal injury.
Check with your process or safety
engineer for any additional measures
that must be taken to protect against
process media.
If installing into an existing
application, also refer to the WARNING
at the beginning of the Maintenance
section in this instruction manual.
The 1008 handwheel actuator can be installed
horizontally, vertically, or at any orientation in
between. However, if supplied with a Tejax position
indicator (see figure 6), the actuator must be
installed in a horizontal position.
When an actuator and valve body are shipped
together as a control valve assembly, the actuator is
normally mounted on the valve. Follow the valve
body instructions when installing the control valve in
the pipeline. If the actuator is shipped separately or if
it is necessary to mount the actuator on the valve,
perform the Actuator Mounting procedures.
Actuator Mounting
Key numbers refer to figure 2 for size 30, figure 3 for
sizes 40 and 50, figure 4 for size 80 or figure 5 for
size 100.
1. Place the actuator on the body bonnet and
tighten the yoke locknut or the actuator mounting
hex nuts.
2. Ensure the valve plug is on its seat.
3. Adjust the travel indicator scale (key 27) so that
the two screws (key 19) are centered in the slots.
4. Screw the hex nuts (key 29) onto the valve plug
stem and place the travel indicator disk (key 20) onto
the stem above the hex nuts. Adjust the nuts until
the travel indicator disk (key 20) points to the closed
position on the scale.
5. Temporarily connect the valve plug stem to the
stem connector assembly (key 24) and tighten the
cap screws into the stem connector.
6. Use the handwheel (key 28) to move the valve
plug into the fully open position, as indicated by the
travel indicator disk (key 20) on the travel indicator
scale (key 27).
7. Remove the stem connector assembly (key 24).
8.
Size 30:
Turn the handwheel (key 28)
counterclockwise until the stem connector assembly
(key 24) almost touches the top of the yoke;
Sizes 40, 50, and 80:
Turn the handwheel (key 28)
counterclockwise as far as it will go;
Size 100:
Turn the handwheel (key 28)
counterclockwise (for push-down-to-close valves) or
clockwise (for push-down-to-open valves) as far as it
will go.
CAUTION
Incomplete engagement of both valve
stem and stem screw assembly (key
