SAFETY PRECAUTIONS
WARNING
Installation and service instructions
are for use by qualified personnel
only. To avoid injury and electric
shock, do not perform any servicing
other than that contained in this
manual. Please read and understand
the appropriate sections in this
manual before attempting to install
or operate your actuator.
STORAGE INFORMATION
The actuator should be stored in its shipping
carton in a clean, dry area.
If it is necessary to store the actuator outdoors
for a long period of time, it should be removed from
its shipping carton and stored above ground. A
waterproof cover should be securely fastened over
it. Do not stack actuators on top of one another.
Stored actuators should be periodically checked
to make sure no condensation has formed in the
control compartments. Damage due to moisture
while in storage is not covered by warranty.
UNPACKING
Group 14 actuators are packed in standardized
cardboard shipping containers. Actuators mounted
on valves may be packed in cardboard containers
or strapped to a skid and crated, depending on
size. After unpacking, the wooden platform may
be used to transport the actuator to the installation
site.
INSTALLATION—MECHANICAL
Beck actuators can be furnished with valves
mounted as unitized assemblies ready for pipeline
installation.
CAUTION
Whenever an actuator is being
mounted on a valve, it is good
practice to remove the valve from
service. Observe the following
precautions:
• Know what fluid is in the line.
• W e a r p r o p e r p r o t e c t i v e
equipment.
• Disconnect the electrical power.
• Depressurize the pipeline.
• Refer to the valve maintenance
manual for specific instructions.
Mounting The Actuator On A
Valve
Refer to the figure below to identify the
mounting parts and the steps to install the
actuator onto the valve.
1. Prepare the valve. It may be necessary to
remove parts that are no longer used or to
replace or adjust packing. Refer to the valve
maintenance manual for specific instructions.
Consult the Beck Valve Mounting Specification
sheet that was shipped with the actuator for
any instructions regarding modifications to the
valve stem that may be necessary.
2. Push the valve stem

into the valve body to
the fully seated or stem down position.
3. Move the G-14 output shaft up into the
actuator body until the upper mechanical stop

is tight against the lower bearing plate

.
4. Remove the four lower bearing plate bolts

that hold the bottom plate to the actuator
body (1/2" bolt heads). Pressure from the
mechanical stop will hold the plate in place
when the bolts are removed. Bolt the yoke

to the lower bearing plate using the longer
bolts supplied with the yoke. Torque bolts to
10 Ib-ft (13.5 N•m).
