What CIRCOR Aerospace does
CIRCOR Aerospace is a privately held manufacturer of highly engineered fluid control, actuation, landing gear, hydraulic, sensor, and weapon release components and subsystems serving commercial aerospace, defense, space, and aftermarket/MRO customers. Headquartered in Corona, California, the business operates through multiple retained sub-brands — Aerodyne Controls, Circle Seal Controls, and LOUD Engineering & Manufacturing — as well as an international footprint via CIRCOR France (CIRCOR Industria, CIRCOR Bodet, CIRCOR Maroc) and CIRCOR Motors. Its product catalog spans check valves, relief valves, solenoid valves, regulators, manifolds, instrumentation valves, hydraulic control and power generation systems, fuel valves, kinetic and pressure switches, AC tachometers, brake pedal transmitters, survival solutions, TruLaunch systems, and weapon release hardware, drawing on 75+ years of fluid control engineering heritage.
The company generates revenue through direct enterprise field sales of qualified aerospace components and subsystems to commercial aircraft manufacturers and defense contractors, supplemented by an authorized distributor network and aftermarket/MRO support for installed platforms. Pricing is quote-based and custom for each engineered component, consistent with B2B flight-critical hardware supply chains. CIRCOR Aerospace is currently owned by KKR, which acquired CIRCOR International (including the Aerospace, Naval, and Industrial segments) in 2023 for approximately $1.6 billion. In May 2026, KKR agreed to sell the aerospace division to Parker Hannifin for $2.55 billion in cash, with closing expected in H2 2026 subject to regulatory approval; KKR will retain the Naval and Industrial businesses, and CIRCOR Aerospace employees are slated to receive dividend distributions from a portion of sale proceeds at close.
