MOC: Multiport Flow Selector Brand Change
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
The Fisher™ Multiport Flow Selector (MPFS) valve connects up to eight input lines,
allowing for the isolation, diversion, and testing of uid from any individual line
through a rotating plug, while the remaining seven lines continue to ow to a
common group outlet. The product provides compact selection and diversion of
uids from individual wells for testing without disrupting the production from all
other wells.
