Screw Stem Actuators

Manually operated fabricated steel handwheels and cranks offer high strength and light weight for easy operation where automatic operation is unnecessary. They are easy to remove, preventing unauthorized operation. Electric motor driven actuators are widely used where speed and ease of operation are desired.
