IMI plc
IMI plc is a Birmingham-based engineering firm founded in 1862, now a precision-engineering and flow-control specialist for critical industries worldwide.
IMI plc
IMI plc was founded in Birmingham in 1862 as a metal-bending manufacturer and has since evolved into a global engineering group focused on precision fluid and motion control. The company designs and manufactures components that regulate the flow of gases, liquids, and steam in demanding environments — serving customers in the energy, transportation, industrial automation, and life-science sectors. IMI's operations span three divisions: IMI Precision Engineering (automation and fluid control), IMI Critical Engineering (valves and actuation for power, oil, and gas), and IMI Hydronic Engineering (energy-efficient heating and cooling systems). The group invests in R&D to develop products that improve energy efficiency and reduce emissions, with a growing focus on renewable energy, electric vehicle charging infrastructure, and hydrogen handling. Notable applications include valves used in nuclear power plants, actuation systems for LNG carriers, and thermal-management components for medical ventilators. The company operates from more than 20 manufacturing sites across Europe, North America, and Asia, serving customers in over 50 countries. As of 2025, IMI employed approximately 10,000 people worldwide. Roy Twite has been CEO since 2020, succeeding Mark Selway. IMI's structural differentiator is its transition from a diversified industrial conglomerate to a focused precision-engineering group with a clear sustainability mandate. The company has divested lower-margin businesses to concentrate on niche applications where engineering complexity and regulatory barriers create competitive advantage. This shift has allowed IMI to capture recurring revenue from aftermarket service contracts and replacement parts, providing stability beyond initial equipment sales.
