In fact, this indicator is mechanically linked to the valve shaft.Travel limit switches• Thanks to the electric actuator camblock system, the adjustment of travel limit switches is simply accomplished with a standard screwdriver.No special tool is required.• Each single cam can be set independently from the others.• The cams are automatically locked in their respective positions, once adjusted, and unaffected by vibrations.Torque sensors• On the AS & BS models, the output torque for valve operation is permanently measured by the lever deflection of the planetary gear external crown.This crown gear is maintained in position by twocalibrated linear springs which can be set independently for each rotational direction to a desired torque value.• In the event the torque setting is reached, the crown lever compresses the spring to a point where a switch is tripped.• As this unique system is mechanically friction-free, exceptional precision and repeatability are obtained, which is highly appreciated when the device has to close on torque.Asynchronous motors• The asynchronous motor technology offers the highest ratio of starting torque versus nominal torque. Thus, the actuator maximum torque capacity is available from the beginning of travel to unseat the valve.Detachable drive bush• The output drive socket can be easily removed from the actuator, without the use of any special tool, for adaptation to the valve shaft.Motor thermal protection• A built-in motor thermal switch protects the motor from overheating.Lubrication• The gear design ensures lifetime lubrication by grease, thus reducing periodic maintenancerequirements considerably.
