INSTALLATION
Inspection
Requirements
Inspect package for damage. If damaged, notify carrier immediately. If undamaged, open
the package and inspect for obvious damage. Return 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 MX40-717X, MX41-707X, MX41-
715X)
– Torque wrench, range to include 55 to 216 lb-in.
– Pipe wrenches, two
– TOOL-37, 1-5/8 inch open-end wrench for valve mounting nut
– 5/16” open-end wrench for jam nuts
– Vise grip or pliers
– Appropriate power supply (see the applicable actuator General Instructions sheet
for power requirements)
Warning:
• Disconnect the actuator power before installation to prevent damage.
• Make all connections in accordance with the job wiring diagram and in accordance with
national and local electrical codes. Use copper conductors only.

General Installation
Mounting
Schneider Electric globe valve linkages are provided as complete assemblies. The following
3
pages contain instructions for installing the AV-602 linkage.
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. 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.
– B2. 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).
– B3. 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, below, to determine the assembly path for the specic actuator and valve.
