CIRCOR International, founded in 1999 and headquartered in Burlington, Massachusetts, is a global provider of mission-critical flow control products and services. The company designs and manufactures highly engineered pumps, valves and fluid handling systems sold into demanding applications across oil and gas, power generation, chemical processing, commercial marine, defense, aerospace and life sciences. It employs approximately 3,100 people, serves customers in over 100 countries and operates a portfolio of 19 brands, many with more than a century of operating history.

The business is organised into three primary groups: Aerospace & Defense, which supplies mission-critical flow control products and services for air, space and defence applications; Industrial Pumps; and Industrial Valves. Product deployments span land and sea operations, air and space applications and underwater or subsea environments. In 2023 the company was taken private by KKR, having previously been listed on the New York Stock Exchange.

Operational performance is managed through the proprietary CIRCOR Operating System, a company-wide framework built on Lean manufacturing principles, quality controls and safety excellence, applied to drive continuous improvement across the brand portfolio. The stated corporate purpose is "keeping society safe, productive and moving", with an emphasis on product reliability and reputation in specification-driven, high-consequence end markets.
