Application
The AV-611 linkage is designed to link the Schneider
Electric SmartX Actuators Mx41-6xx3 (non-spring
return) and Mx40-704x (spring return) shown in Table-1
to 1/2” through 2” VB-7xxx and 1/2” through 1-1/4”
discontinued VB-9xxx 2-way and 3-way globe valves.

Inspection
Requirements
Mounting
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 any
damaged products.
• Training: Installer must be a qualied, experienced technician.
• Tools (not provided):
– Appropriate wrenches for stem extensions, packing nuts, and bracket nuts
– 10 mm socket wrench (for shaft clamp nuts on Mx41-6153 and Mx40-704x)
– Torque wrench, range to include 60 to 120 lb.-in. (6.8 to 14 N-m)
– Pipe wrenches, two
– TOOL-37, 1-5/8 inch open-end wrench for valve mounting nut
– 5/16” open-end wrench for jam nuts (or TOOL-20-1 or equivalent)
– Vise grip or pliers
– Appropriate power supply (see the applicable actuator General Instructions sheet
for power requirements)
Warning:
• Disconnect the power supply (line power) before installation to prevent equipment
damage.
• Make all connections in accordance with the job wiring diagram and in accordance with
national and local electrical codes. Use copper conductors only.
Allow at least 5” (127 mm) above the actuator/linkage assembly for removal and
reattachment of the actuator to the installed valve.
Assembling Actuator
and Linkage to Valve
Body
Process Overview
This assembly procedure consists of two sections:
• Section A. Assembling Linkage to Valve — All Valve Types and Actuator Models
For all actuator models and valve types (2-way and 3-way), follow the instructions in
this section to assemble the linkage to the valve.
• Section B. Actuator Mounting and Setup
In this section, choose the subsection that is appropriate for the specic actuator type
and valve type, to mount the actuator and adjust the linkage:
– B1. Mx41-6043 and Mx41-6083 Non-spring Return Actuators with Manual
Override — 2-Way (Stem Up Open, Stem Up Closed) and 3-Way Valves
These instructions apply to actuators with manual override, to be mounted onto
2-way valves (stem up closed and stem up open) and 3-way valves
– B2. Mx41-6153 Non-Spring Return Actuators with Manual Override — 2-Way
Valves (Stem Up Closed and Stem Up Open) and 3-Way Valves
These instructions apply to actuators with manual override, to be mounted onto
2-way valves (stem up closed and stem up open) and 3-way valves.
– B3. Mx40-704x Spring Return Actuators without Manual Override — 2-Way
Valves (Stem Up Closed and Stem Up Open)
These instructions apply to spring return actuators, to be mounted onto 2-way
valves (stem up closed and stem up open).
– B4. Mx40-704x Spring Return Actuators without Manual Override — 3-Way
Valves
These instructions apply to spring return actuators, to be mounted onto 3-way
valves.
Refer to Table‑2, on the next page, to determine the assembly path for the specic actuator
and valve.
