M Series Actuators
M Series Manual Handwheel Gear Actuators for Type A11, A31A and A41 Butterfly Valves
M Series handwheel gear actuators (figure 1) are totally enclosed, weatherproof, worm gear actuators for reliable manual operation with Type A11, A31A and A41 High Performance Butterfly Valves. The M Series actuator consists of a body housing, cover, worm gear, input shaft, and handwheel. The housing is grease-packed.

Neither Emerson, Emerson Process Management, nor any of their affiliated entities assumes responsibility for the selection, use and maintenance of any product. Responsibility for the selection, use, and maintenance of any product remains with the purchaser and end-user.
Features
D Long Service Life—Rugged construction
provides stability and corrosion resistance. The unit is totally enclosed for weatherproof operation.
DAccurate Valve Disc Positioning—Two adjustable stops are located in the housing for correct adjustment of disc position. The actuator is inherently self-locking, unless subjected to high vibration.
DOvertravel Capability—Provides for five degrees of overtravel in both directions for precise positioning of the valve disc.
Installation
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 Type A11 or A31A and it can be mounted in positions 1 and 3 on the Type A41, as shown in figure 2. Make clearance considerations before mounting the actuator to determine the most suitable mounting position. Dimensions are shown in figure 3.

1. Maximum recommended torque for the valve/actuator combination is based on valve shaft rating, actuator rating and rim force. 2. Rim force required to produce Maximum recommended torque.
3. This column shows the number of times the handwheel must be turned to close the valve 90 degrees. 4. Shaft rating of the A11 valve.
Ordering Information
Because the M Series actuators for the A11 and A31A valves are often available in more than one size for any given valve size, they should be chosen according to torque requirements of the valve.
Please specify actuator size when specifying valve size and class.
M Series actuators for the A41 valve have been matched to the requirements of each valve size and should be chosen according to the valve size requested.
