Power Drive Damper Drives are manufactured, assembled and tested in our Loveland, Ohio facility

After the shop receives the design drawings, the parts are machined to the required dimensions, holding the design tolerances. During the assembly process each part is fit checked to ensure proper performance. Once assembled, any mechanical stops are adjusted, limit switches are set, positioners and transmitters are calibrated.

Other Power Drive damper drives are also available as electric or electro-hydraulic drives.
