Valmet has completed the acquisition of Severn Group, an industrial valve company specialising in severe service flow control solutions, boosting its Flow Control business area.
Valmet Flow Control serves a broad customer base including those in the mining and metals space.
The acquisition was announced on December 22, 2025, and it covers all three Severn divisions: Severn Glocon, ValvTechnologies and LB Bentley.
Severn’s capabilities and customer relationships strengthen Valmet’s Process Performance Solutions segment, which already accounts for close to half of Valmet’s profitability, the company says. The acquisition further accelerates growth beyond the company’s traditional core biomaterials business.
Thomas Hinnerskov, President and CEO of Valmet, said: “This is an important milestone in the execution of Valmet’s Lead the Way strategy, strengthening the Process Performance Solutions segment and expanding our Flow Control business. Severn strengthens our business in three ways: it adds a new addressable market in refining, energy and metals, it brings an installed base whose aftermarket potential we can unlock through Valmet’s lifecycle service model and it expands our technology in severe service flow control.
“We are proud to welcome around 950 new colleagues to Valmet, bringing valuable expertise and capabilities that help reinforce our position as a strategic partner delivering lasting customer value across the entire lifecycle.”
Severn will now be integrated into the Flow Control business area, further enhancing Valmet’s position as a leading provider of mission-critical valve and valve automation solutions across global process industries, it says.
The acquisition expands Valmet’s flow control portfolio and enhances its ability to support customers in the global energy transition. Combined with Severn’s strong expertise in the most demanding applications, Valmet’s Flow Control business area serves a broad customer base throughout the oil and gas value chain, as well as in chemicals, renewable energy, power generation, biomaterials, mining and metals, and subsea applications.
Simo Sääskilahti, Executive Vice President, Flow Control business area at Valmet, said: “Valmet’s existing valve solutions and the application know-how of the Severn businesses complement each other well, creating a truly unique offering for severe service flow control, which is especially critical for the energy segment. With our combined capabilities, we are well positioned to support our customers in ensuring the availability of energy and critical raw materials, while also advancing the transition toward more sustainable and resilient energy systems.”
Severn Group generated net sales of approximately €215 million ($245 million) in 2025, with an EBITDA margin of approximately 16%. The transaction is valued at $480 million on a cash- and debt-free basis.
