Spring to Centre Actuators

Kinetrol's spring to centre models have a patented part-turn rotary actuator that is driven to an end stop in any direction from an initial centre position. Once the air supply is removed, it’s spring returned to an accurate and positive midpoint. The operator can mechanically choose this mid-position.
