Scope of Manual
February 2019
This instruction manual includes installation, operation, maintenance, and parts ordering information for M Series
manual handwheel gear actuators. Refer to separate manuals for instructions covering the valves used with these
actuators.
Do not install, operate, or maintain an M Series handwheel gear actuator without being fully trained and qualified in
valve, actuator and accessory installation, operation and maintenance. To avoid personal injury or property damage it
is important to carefully read, understand, and follow all of the contents of this manual, including all safety cautions
and warnings. If you have any questions about these instructions, contact your Emerson sales office
proceeding.

Description
M Series handwheel gear actuators (figure 1) are totally enclosed, weatherproof, worm gear actuators for reliable
manual operation with Fisher A11, A31A and A41 High Performance Butterfly Valves. The M actuator consists of a
body housing, cover, worm gear, input shaft, and handwheel. The housing is grease packed.
Specifications
Specifications for the M Series manual handwheel gear actuators are shown in table 1.

See figure 2
J Accepts A41 valve Double D shafts from 12.7 to
44.5 mm (1/2 to 1‐3/4 inches)
Dimensions and Approximate Weights
See Bulletin 22.2:M
Maximum Torque Output
See Bulletin 22.2:M
Options
J Locking plates with padlock for fixed positioning
Handwheel Rotation
Clockwise handwheel rotation closes the valve
(produces clockwise rotation of the valve shaft)
1. As an option, CL600 NPS 10 (with 1‐1/2 inch keyed shaft) and NPS 12 (with 1‐3/4 inch shaft) A11 valves require a keyed connection if being used with size 9KE or 10KE‐6 actuators.
J Stops are typically set every 10_, but can be special
ordered with stops set up to 45_ from both ends
J Handwheel extensions

Installation
WARNING
To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the actuator
where service conditions could exceed the limits given in this manual or on the appropriate nameplates. Use
pressure‐relieving devices as required by government or accepted industry codes and good engineering practices.
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
The M Series gear actuator is normally mounted on a valve at the factory. However, the actuator can be field mounted;
it can be mounted in any position on the A11 or A31A and it can be mounted in positions 1 and 3 on the A41, as shown
in figure 2. Make clearance considerations before mounting the actuator to determine the most suitable mounting
position.
The M Series actuator has a direct stab‐on design. Simply insert the valve shaft into the broached area of the body
housing. Then attach the mounting bracket to the actuator, using the torques listed in table 5, and attach the
mounting bracket to the valve.
