Valves & Flow Control

Data Centers Have Become a Structural Demand Driver Across the Sector

Data center-related revenue doubled year-over-year at Core & Main, reaching a mid-single-digit share of total sales, while Watts Water reported data center sales at high single digits of total company revenue in Q3 2026 with accelerating momentum. IDEX's data center, semiconductor, and space and defense verticals collectively exceeded one-third of portfolio weight and delivered approximately 50% year-to-date organic growth, and Flowserve management described meaningfully different customer conversations around liquid cooling compared to the company's historically minimal data center presence. This demand is contracted and project-driven, not anticipated: Core & Main is shipping against booked data center infrastructure orders, and Watts Water is building strategic inventory specifically to support hyperscaler facility demand.

Middle East Conflict Has Crossed from Headwind to Structural Revenue Risk

Flowserve cut its full-year organic sales outlook to a decline of 1.5% to 2.5%, attributing approximately $40 million in Q3 revenue loss to escalating Middle East conflict that has expanded into areas with a higher concentration of its installed base. ITT's 10-Q introduced a new risk factor explicitly naming the February 2026 US-Israel military strikes against Iran and Strait of Hormuz disruption risk, language absent from its 2025 Annual Report, while Emerson's FY2027 guidance explicitly assumes status-quo conflict conditions and models an approximately $85 million revenue headwind if conditions deteriorate. Franklin Electric reported organic international volume down approximately 5% in Q3 2026 from conflict-related softness in Northern Africa, the Middle East, and Eastern Europe, and Watts Water cited the conflict as a material APMEA headwind.

Nuclear and Power Infrastructure Are Repricing the Valve Segment's Growth Ceiling

Flowserve reported nuclear bookings exceeding $115 million in Q3 2026, the fourth consecutive quarter above $100 million, and its Flow Control Division backlog grew 33% in nine months to $1.1 billion following the $490 million acquisition of Trillium Flow Technologies' Valves Division. Crane's Process Flow Technologies segment reported 20% year-over-year core order growth in Q3 2026, with power and nuclear now representing approximately 15% of segment revenue, up from a lower base, and chemical exposure reduced from 30% to approximately 20%. Emerson's approximately $2.5 billion power business grew 25% in FY2026, with the control systems portion up close to 45% in Q4, and Ovation orders up 26%, confirming that nuclear and power infrastructure are driving a multi-year capital formation cycle rather than a maintenance cycle.

Portfolio Simplification Is Accelerating as a Margin Strategy Across the Sector

Mueller Water Products exited its metering business entirely, transitioning customers to Zenner USA and projecting 100 to 140 basis points of annualized adjusted EBITDA margin expansion beginning in Q2 FY2027, after the business declined at a 10% CAGR over four to five years with negative EBITDA margin. Crane announced the divestiture of its Building Services and Utilities business for GBP 230 million while simultaneously acquiring Trillium Pumps to reweight Process Flow Technologies toward water and wastewater. Watts Water's 80/20 rationalization has reduced residential exposure from 40% of 2022 sales to approximately 25% in 2026, with nonresidential and data center now representing 75% of projected 2026 sales. These are not cost programs; they are deliberate portfolio exits that are structurally repricing segment margins upward.
