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.

Instruction Manual

D500237X012

M Series Actuator

February 2019

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.
