Our History

Centered Image

Aunspach Controls Company was founded in 1986 by Dale Aunspach, who grew up in the valve industry and recognized the need to protect valves, actuators and other equipment from damage caused by excessive operating torque. The first efforts were to provide overtorque protection products for municipal water distribution valves. Users include many major and smaller North American cities.


As the company grew, it entered the industrial fluid processing and handling markets. Products are currently in service in nuclear and fossil-fueled power plants, refineries, off- shore facilities, pipelines, municipal water systems and other venues.

Further growth brought the company into the mechanical power transmission market to include protection of conveyors, packaging and other machinery.


Aunspach Controls Company has customers and products on five continents. The products have a more than 30-year record of dependable performance and long-term reliability. They are well suited for severe service in dirty and corrosive environments. Most products can be buried, submerged and require no regular maintenance. A large inventory of finished and semi-finished goods is on hand at all times for immediate or short-lead shipment.
