Application
The AV-390 through AV-396 linkages are used to field assemble Schneider Electric gear train actuators to VB-7XXX series or VB-9XXX series valve bodies.
• AV-391 and AV-393 are used with cu rrent 1/2" to 2"
VB-7X1X and obsolete 1/2" to 1-1/4" VB-9X1X
valve
bodies.
• AV-392 and AV-394 are used with obsolete
1-1/2" and 2" VB-9X1X valve bodies.
• AV-395 and AV-396 are used with current 2-1/2" to
4" VB-9X1X valve bodies.

Temperature Restrictions
Verify that the fluid temperature of the media in the valve versus the ambient temperature at
the actuator does not exceed the ratings shown in
Table-2 Restrictions on Maximum Ambient Tem perature for Actuators.

Close-off Pressure Rating
Close-off pressure ratings are listed in Table-2 and Table-3. Check the appropriate table to
verify that the selected valve, valve linkage, and actuator provide adequate close-off
pressure for your application.
Required Components
The actuator, valve, and valve linkage should be purchased separately. See Table-2 and
Table-3 for selections.
INSTALLATION
Inspection Inspect the package for damage. If damaged, notify the appropriate carrier immediately.
If undamaged, open the package and inspect the device for obvious damage. Return
damaged products.
Requirements • Tools (not provided):
– Appropriate wrenches for stem extensions, lock nuts, packing nuts, and brackets
– Appropriate screwdriver for actuator mounting screws
– TOOL-37, 1-5/8" open-ended wrench with a maximum thickness of 3/16"
• Training: Installer must be a qualified, experienced technician
Caution:
• Avoid locations where excessive moisture, corrosive fumes, or vibration is present.
• Install all two-way valves so that they close against the flow. An arrow on the valve body
or a tag indicates the proper flow direction.
• Always install three-way mixing valves with two inlets and one outlet.
• Always install three-way diverting valves with one inlet and two outlets.
• The actuators can be mounted in any position above the centerline of the valve body.
For steam applications where the ambient temperature approaches the limit of the
actuator, the valve stem should be mounted 45° from vertical. When selecting a
location, allow sufficient room for accessories and for service of the product.
