This year marks the 60th year that the Circle Seal Controls, a CIRCOR Aerospace business, has designed and manufactured innovative solutions to the fluidic controls requirements of our industrial and aerospace customers.

Circle Seal has been a fixture in Southern California since 1947, with an original manufacturing facility in Pasadena and subsequent years at an Anaheim location. The company now calls Corona, California home at a state of the art facility off the CA 91 freeway.

The business plans a day of recognition in November and expects key customer and government dignitaries to be in attendance. The Corona operations employ over 300 dedicated professionals, delivering critical fluid flow control devices for military and commercial aircraft, US Navy ships, the Space Shuttle and other rocket and missile applications.

Circle Seal Controls products can be found on applications including the Boeing 737 Passenger Aircraft, Lockheed Martin F/A-22 Raptor Advanced Air Superiority Fighter, US Navy Littoral Combat Ship and Northrop Grumman Global Hawk Unmanned Aircraft.

A full range of check, relief, motor operated, solenoid operated, hand, regulator and fluid manifold systems are available to meet demanding requirements. These devices are employed to control a wide variety of fluids including hydraulic oils, aviation fuels, water, air and other gases for extreme temperature and pressure conditions.
