Cameron valve products have been known for their reliability and durability for decades.

Complement your Cameron valve with a range of DYNATORQUE valve accessories and MAXTORQUE high-performance valve products.

To us, customer focus means our products are backed by our commitment to customer needs:

  • Customized products are no problem. We provide different frame and spur combinations, a wide variety of material options, one-off capability, and rapid turnaround.
  • Onsite static and dynamic-load test benches create accessories that will perform in trying real-world applications.
  • Attention to quality is at every level of the manufacturing process. We follow rigorous approval standards for material sourcing, perform preproduction and postproduction inspections, and are ISO certified.



LEDEEN actuators have provided exceptional valve automation performance to the oil and gas industry since 1948. We've since gained exposure to a wide range of operational conditions and accumulated extensive first-hand application experience, enabling us to provide field-proven solutions known to be fit for purpose and reliable.

We obtained valuable product knowledge through years of successful operations in challenging desert, arctic, offshore, and subsea applications. Relying upon this extensive global experience and applying it during the evaluation of every requirement is a commitment to best practices that benefits every customer working with Cameron.
