Emerson Acquires Valve Control Specialist TopWorx

The acquisition extends Emerson’s PlantWeb digital plant architecture and complements Emerson’s valve and instrument businesses.

Emerson Electric Co., St. Louis, announced on July 8 that it has acquired TopWorx Inc., a Louisville, Ky.-based supplier of valve control and position sensing solutions. TopWorx becomes part of Emerson Process Management, the Austin, Texas-based process automation vendor, expanding the company’s valve instrument offering and extending the reach of Emerson’s PlantWeb digital plant architecture to on/off valves and other instruments. Terms of the TopWorx acquisition were not disclosed.

TopWorx manufactures industrial sensors and controls that monitor and control automated valves and other field devices. TopWorx Valvetop discrete valve controllers connect on/off valves to a variety of fieldbus networking protocols, and GO Switch leverless limit switches are designed to provide reliable position sensing in harsh environments and tough applications. The company has additional locations in the United Kingdom, Singapore, and South Africa.

“TopWorx is a strong and growing business that is highly valued by its customers,” said John Berra, president, Emerson Process Management. “The acquisition gives us a quick and significant entry into the discrete instrumentation market, and is highly complementary to our existing valve, valve automation, and instrument businesses. TopWorx will extend the benefits of our PlantWeb digital plant architecture, and enable us to provide a complete valve instrument portfolio, both wired and wireless.”

“It is exciting to join what I consider the best and most progressive company in our industry,” said Charlie Marcum, president of TopWorx. “Emerson Process Management’s global reach and technology leadership will accelerate our growth and broaden our product offering, enabling us to serve customers even better than before.”
