DALLAS–(BUSINESS WIRE)– Flowserve Corporation (NYSE: FLS) (“Flowserve” or the “Company”), a leading provider of flow control products and services for the global infrastructure markets, has signed a definitive agreement to acquire Trillium Flow Technologies’ Valves Division¹ (“TVD”), a market leading provider of highly engineered mission-critical valves used in nuclear and traditional power generation, industrial, and critical infrastructure applications for $490 million in cash (the “Transaction”). The Transaction is expected to close mid-year 2026.

TVD’s comprehensive portfolio of brands serves a global customer base across attractive and growing end markets with a nearly 200-year legacy of engineering excellence and reliable performance. The acquisition will expand Flowserve’s reach in both conventional and emerging markets by integrating TVD’s highly specialized valve and actuation product portfolio, differentiated power and nuclear technology, and scalable service offerings.

TVD’s large installed base of over 200,000 units, including assets in 115 operating nuclear reactors, generates recurring, high-margin demand for aftermarket services, replacements, and spare parts. Adding TVD’s portfolio strengthens Flowserve’s leading nuclear position—supporting more than 300 reactors worldwide—and enhances the Company’s ability to serve existing nuclear assets while delivering a broad range of flow control solutions for new traditional and small modular reactors.

“TVD’s products and capabilities are highly complementary to our portfolio and will enhance our ability to meet future demand in nuclear, traditional power, and more broadly across the industrial landscape,” said Scott Rowe, Flowserve President and Chief Executive Officer. “We see strong aftermarket potential from their global installed base that is expected to drive profitable growth. The acquisition underscores our commitment to building a more cycle-resilient business and will enhance value for shareholders, customers, and associates. We look forward to welcoming the Trillium Valves team to Flowserve.“
