The AmurAct is available with two
versions of Linkage. The standard
version or LS linkage has the mo-
tor situated directly behind the
linkage assembly with the Amu-
rAct actuator unit oriented parallel
to the pipeline This configuration
of the linkage is suitable for pro-
cess fluids up to 250F (steam to
15 PSIg) when the pipeline and
valve are not insulated, or up to
340F (steam to 100 PSIg) when the pipeline and valve are
insulated.
For higher temperature applica-
tions or for when insulation is not
available the higher temperature
linkage can be used. This is capable
of operating up to the valve rated
temperature, without regard to in-
sulation. For temperatures above
500F this may require the use of
the optional extension bonnet as
well. In this version, the motor is
oriented 180° away from the stan-
dard orientation, and the entire assembly is mounted per-
pendicular to the valve and pipeline, avoiding convected
heat from the valve and process piping, ensuring safe, reli-
able operation.
REMOVING AN AMURACT
MOTOR
1
Shut the isolation valves both upstream and downstream of
the AmurAct control valve. If the control valve is not isolated,
line pressure can open the valve and move the linkage when
the motor is removed.
2
Turn off power to the motor and controller.
3
Remove the black motor cover and dissipate Enerdrive
energy by cycling dipswitch #2 in 20-second intervals until
the motor no longer runs. Return dipswitch #2 to its ON
position (Fail Shut).
4
Remove the front safety shield by removing the two screws
from the lower edge of the AmurAct linkage.
5
De-clutch the motor by depressing the brass pin located
in the center of the circuit board as shown on page 6 and
manually rotate the CRANk to its counter-clockwise end
of travel position, as defined in specific linkage calibration
procedures. Install a c-clamp to hold the CRANk in that
position.
6
If the same motor is to be reinstalled, proceed to step 7. If
it is to be replaced, label field wires for reconnection, then
disconnect and remove them.
7
Loosen the two 10 mm hex nut on the motor output clamp u-
bolt. This is best done with a long socket or box end wrench.
Nuts are very tight. (It may also be necessary to loosen the
kep nut and loosen or remove the anti-rotation screw located
at the foot of the motor.)
8
Remove the motor. Review linkage calibration on pages 13-
15 to verify linkage is calibrated and valve stem nuts are tight.

CAUTION
Do not de-clutch the actuator when power is on.
Irreparable damage to the gear train will occur!
