Introduction
Scope of Manual
This instruction manual includes installation, operation, and maintenance information for the Fisher 1078
declutchable manual actuator (figure 1). Refer to separate instruction manuals for instructions covering the power
actuator and control valve.
Do not install, operate, or maintain a 1078 declutchable manual 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 the contents of this manual, including all safety cautions
and warnings. If you have any questions about these instructions, contact your Emerson Process Management sales
office before proceeding.

Handwheel Rotation
Direct Acting Construction: Clockwise handwheel
rotation closes the valve (produces clockwise valve
shaft rotation)
Reverse Acting Construction: Clockwise handwheel
rotation closes the valve (produces counterclockwise
valve shaft rotation)
Decide whether Direct or Reverse Action is required
by referring to the appropriate valve or power
actuator instruction manual and determining valve
rotation.

Description
The 1078 manual actuator, shown in figures 1 and 2, is a declutchable unit for manual operation of control valves and
equipment that use power actuators. The 1078 manual actuator mounts directly to Fisher 1051 sizes 33, 40, and 60;
1052 sizes 33, 40, 60, and 70; 1061 sizes 30, 40, 60, 68, 80, and 100; and to all sizes of 1066 or 1066SR actuators. The
1078 manual actuator can be engaged to allow manual operation of the valve when the power actuator is not in use. It
can be disengaged to allow automatic operation of the valve by the power actuator. The mechanism used allows
manual actuator engagement at any point of power actuator rotation.
For 1051 size 33, 1052 size 33, 1066, and 1066SR actuators, coupling to the power actuator is via a flatted shaft
installed in the lever or hub. The dimensions of these shafts are the same as those used with H mounting adaptations.
The stub shaft fits into a square broach in the manual actuator sector, and spacers secure the shaft in the appropriate
position.

H and J mounting adaptations are the mounting methods normally used to mount 1051, 1052, 1061, 1066 and
1066SR actuators on equipment and valves not manufactured by Emerson Process Management. F and G mounting
adaptations are the mounting methods normally used to mount 1051, 1052, 1061, 1066 and 1066SR actuators on
valves manufactured by Emerson Process Management.
For all sizes of the 1066 or 1066SR actuators, coupling to the power actuator is in the hub of the 1066 or 1066SR
actuator.

Specifications
1078 manual actuator specifications are given in table 1. Specifications for a control valve assembly as it comes from
the factory appear on a nameplate attached to the power actuator.

2. Field conversion of actuators for F and G mountingadaptations requires installation of new parts. The 1051 or 1052 Size 33 actuator requires installationof appropriatelever and stub shaft.
The 1066 actuator requires installation of appropriate hub assembly.
3. Compare table value with torque requirements of the valve plus the torque requiredto compress the power actuator spring (from FisherCatalog 14). Note that dynamic torqueof the valve
may have a positive or negative effect on total torque required.
