About Williams Controls

A legacy brand under the Curtiss-Wright Industrial Division, William Controls is one of the leading suppliers of parts and sub-systems, providing customers with specific solutions for their on- and off-highway vehicles. Williams Controls Inc. was established in 1937 as a manufacturer of vacuum water valves used to keep the brake drums of logging trucks and trailers in proper operating temperature. It was founded in Portland, Oregon, by Norman C. Williams. In 1962, Williams Controls launched its first pneumatic throttle control system, eliminating the need for long, complex mechanical linkages.

To address the customers' needs for increased efficiency and reduced emissions, the company introduced the first electronically controlled diesel engines in the mid-'80s. By working closely with different engine and automotive manufacturers, Williams Controls' developed the first electronic throttle control in 1987. With this breakthrough, the company quickly rose to success and became globally recognized as a world leader in designing and manufacturing electronic throttle controls for trucks and buses while strengthening its position in off-highway markets.

Williams Controls had its presence felt in the international arena when it opened strategic sales and customer service centers in China, Germany, and India. On October 31, 2012, Williams Controls was acquired by Curtiss-Wright. This premier engineering company delivers well-engineered, critical-function components, systems, and services for flow and motion control and metal treatment applications in the energy, defense, and industrial markets.
