3. How to properly operate a three-phase motor using single-phase power

There are several methods to operating a three-phase motor using single-phase power to make what would be an otherwise expensive and arduous process a little easier.

4. Butterfly valve basics

Inside Process: Like other types of valves butterfly valves interrupt product flow within processes. Typically used in pharmaceutical, chemical, and food industries, they have generally replaced ball valves due to lower cost and ease of installation.

5. The benefits of calculating ROI to measure a facility’s performance objectives

For automation, return on investment (ROI) is more important than total cost of ownership (TCO). When making a capital investment in automation, companies need to determine value based on the solution’s impact on facility performance and its workforce. Also consider cost of downtime and services.

The list was developed using CFE Media’s web analytics for stories viewed on controleng.com, October 31 to November 6, for articles published within the last two months.
