Kobelt's initial product line started in the early 1960's with mechanical and pneumatic controls for marine vessels, including actuators, control heads, air cylinders and various other parts and components. The 900 series actuator was an early success, with some units still being used 30 to 40 years later. From its inception, Kobelt has used bronze extensively throughout all parts and components to ensure product longevity. By 1967, Kobelt had just under 100 products, and could supply complete systems for propulsion control in both mechanical and pneumatic environments.
