Management of Change
Management of Change (MOC) is a procedure used to proactively manage changes
that have the potential to impact safety or the process within a plant. Evaluating
new techniques for improving MOC approval procedures can have an impact on
plant efciency. Historically, upgrading obsolete products or replacing existing
process control equipment had been delayed or abandoned due to the extensive
paperwork involved in completing a complex MOC approval sheet.
Background
Emerson introduces the Fisher G Series pneumatic scotch-yoke actuator. The Bettis
G actuator has been used across multiple industries in both on/off and control
applications for many years. The Fisher G actuator will continue to serve those same
applications when installed on a Fisher valve.

Branding
The G Series product branding and badging will be Fisher if purchased assembled
on a Fisher valve at an Emerson manufacturing or service location. For service
and repair work, the product badging will remain the same as it was prior to the
maintenance event. New G Series actuators supplied from an Emerson Lifecycle
Service location will be Fisher G Series actuators.
