With stroke lengths of up to 50mm and 100mm, they are well-suited for HVAC systems, industrial automation, and high-temperature equipment such as boilers and heating systems.

Each linear actuator comes with a manual override for swift manual valve operation. A position indicator at the drive stem area ensures valve position identification. The stroke is adjustable to match valve stem travel within the rated length.
