Cameron LEDEEN* actuators and control solutions have consistently provided exceptional valve automation performance to the oil and gas industry since 1948, when we introduced a robust product design based upon solid engineering principles with a commitment to continuous improvement. Each successive year was guided by those foundational principles, enabling us to gain exposure to a wide range of operational conditions and to accumulate extensive firsthand application experience.This resulted in the ability to provide field-proven solutions that are known to be fit forpurpose and reliable.
