Rotary Actuator Technology for Industrial Applications Available at Moog

Moog has grown in capabilities in the last 10 years greatly through a series of strategic acquisitions that enhance our motion control technologies and scope of supply. One acquisition we wanted to share with our customers is Moog Flo-Tork as it has many capabilities that are of interest to our industrial customers.

Who is Moog Flo-Tork?

Since its inception in 1957, the name Flo-Tork has been associated with rotary actuator applications and the company gained a reputation for original approaches to motion design technology. These achievements were made possible by a strong engineering staff that enables the company to custom design components and tailor unique materials, tolerances and design specifications to each customer's needs.

Currently employing 68 full time personnel, Moog Flo-Tork has a 9300 square meter (100,000 square foot) manufacturing facility in Orrville, Ohio, USA where it uses lean manufacturing and the latest technologies to ensure quality and efficient production. Moog Flo-Tork’s capabilities extend from very small actuators 11 Nm (100 lb-in) to very large 5.6 million Nm (50,000,000 lb-in) and beyond. Moog Flo-Tork is constantly working to improve its manufacturing and engineering capabilities to meet global demands.

History of Moog Flo-Tork

Founded in 1957, Moog Flo-Tork grew in the 1960's and 1970's through its military and industrial fluid power applications. In the mid-1980's Flo-Tork. recognized the need to diversify to continue its consistent growth philosophy. In analyzing its capabilities and the needs of an ever changing marketplace Flo-Tork decided to place stronger emphasis on the valve actuation market. In addition to the current rack and pinion product offering the company acquired an improved Scotch-Yoke and an electro-mechanical rotary actuator product line for valve and damper applications.

In 2005, Flo-Tork was acquired by Moog to increase our product offering. The two companies had been collaborating on projects, and it was a natural fit. As part of Moog, the ability to market the Moog Flo-Tork industrial actuators has increased due to the global presence Moog offers, and has opened many new opportunities in different areas of the world.
