Introduction
Scope of Manual
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 before
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.

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.

Operation
After the actuator and control valve assembly are installed, the manual actuator is ready for operation.
CAUTION
Applying too much torque to the actuator and valve parts could cause damage to the parts. To avoid such damage, do not
exceed the rim force listed in table 2, 3 and 4 or any other torque limitation of internal valve parts. Also, do not use
wrenches or other devices on the handwheel or handwheel shaft to increase operating force.
Maintenance
WARNING
Avoid personal injury from sudden release of process pressure. Before performing any maintenance operations:
D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
on both sides of the valve. Drain the process media from both sides of the valve.
D Vent the power actuator loading pressure and relieve any actuator spring precompression.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the
pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when
loosening the packing box pipe plug.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.

If the rim force required to rotate the handwheel exceeds the rim force listed in table 2, 3, or 4, check for the following
conditions:
D Insufficient lubrication
D Seized actuator parts
D Excessive pressure drop across the valve
D Obstruction to the valve disk rotation
If the manual actuator does not seem to control the process fluid, the worm or drive sleeve gear teeth may be broken,
the handwheel pin may be sheared, or the valve parts may be broken. Purchase a replacement manual actuator if
necessary. Refer to the valve instruction manual if valve maintenance is needed.
Lubrication
The interior parts of the M Series actuator should be lubricated on a regular schedule with a quality gear lubricant. The
interior parts should also be lubricated whenever difficulty in handwheel rotation indicates a need for lubrication.
1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the
process media from both sides of the valve.
2. Remove the cap screws that secure the gearbox cover plate and remove the gearbox cover plate.
3. Coat the worm, the drive sleeve gear teeth, and the bearing surfaces of the gearbox housing and worm with a
quality gear lubricant.
4. Replace the cover plate and cap screws using the bolt torques listed in table 5.
5. Replace the manual actuator on the valve. Adjust the actuator travel stop to limit the open and closed positions of
the valve disk following the steps in the appropriate valve instruction manual.
Parts Ordering
When corresponding with your Emerson sales office indicate the size of the M Series actuator. The size is stamped on
the gearbox. You should also provide the serial number of the valve.
WARNING
Use only genuine Fisher™replacement parts. Components that are not supplied by Emerson Automation Solutions should
not, under any circumstances, be used in any Fisher valve, because they will void your warranty, might adversely affect the
performance of the valve, and could give rise to personal injury and property damage.
