Feature: Torque limitation by controlled friction clutch
Functional princliple
Cut drawing
Torque enhancement
Advantage of the controlled friction clutch instead of a moving worm can be seen easily in the graphics shown below. Reason of this advantageous construction principle is that in case of switch of failure the maximum allowable torque is never exceeded and a damage of the driven valve is avoided.
