IMI Group Breakthrough Engineering tagline

IMI Critical has long been recognised as a world-leader in the provision of flow control solutions. Our products allow vital industries to operate safely, cleanly, reliably and efficiently, so that they can provide us with the energy, resources and materials that underpin modern lives.

IMI Critical’s family of specialist companies design, manufacture and service bespoke valves and actuators that precisely control the flow of steam, gas and liquids under extremes of pressure and temperature, as well as intensely abrasive or corrosive operating conditions.

Our valves can be found in a myriad of industrial plants and processes around the world, enabling the production of oil and gas, power, petrochemicals, metals, pharmaceuticals, cosmetics, food and beverages, water and sanitation, pulp and paper, ethanol and sugar. Our products are also widely deployed on ships and submarines.

Our engineering expertise means that we can make hazardous processes safer, cleaner and greener. By helping clients reduce emissions, improve safety, and make processes more efficient, we have a direct and positive impact on the world. That is why we describe our purpose as ‘breakthrough engineering for a better world’.


Customer Focus

We pride ourselves on our ability to work in partnership with clients to overcome their most demanding engineering challenges, and aim to deliver bespoke solutions that help clients maximise safety, efficiency and reliability, while also meeting ever tougher environmental standards.

IMI Critical’s clients can also benefit from the expertise of our Valve Doctors™ to help them solve their most intractable problems. Our Valve Doctors™ are amongst the best engineers in the business, and combine advanced engineering and technical expertise with industry and application knowledge. Meanwhile our team of Field Service engineers can carry out on-site maintenance and upgrades of installed valves.

Product Principle

Customers choose IMI Critical because of our engineering knowhow and manufacturing expertise built over decades. With over 750,000 valves, including 250,000 bespoke valves, installed in critical industrial plants and processes worldwide, no-one knows more than IMI Critical about operating hazardous processes safely, efficiently and with minimum environmental impact.

Our in-house expertise includes valve design and engineering, manufacture, testing, installation and service. Our knowledge of plant operation and system layout means we can recommend the best solution and materials for any given situation, ensuring reliable and efficient plant performance. As well as established technologies such as DRAG®, technology acquired from Sulzer and BTG valves and isolation technology from IMI Orton and IMI Truflo Italy, we offer innovative techniques such as additive manufacturing (or 3D printing) through our Retrofit3D business to upgrade existing and competitor valves.
