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
Fisher™ 2625 volume boosters are found in almost every industry and have an
extensive service history. Volume boosters are used to amplify the pneumatic
positioner output to an actuator, thereby increasing the speed and responsiveness
of a valve actuator. As many as three 2625 volume boosters can be replaced with
just one Fisher SS-263 volume booster, reducing the size and complexity of the
installation. The purpose of this guide is to simplify the transition from existing
2625 volume boosters to new SS-263 volume boosters.
