Servo Motor Valve Waterproof Bernard Control Valve Electric Actuator

"Servo Motor Valve Waterproof Bernard Control Valve Electric Actuator" is listed under  ValvesCategory

Product DescriptionBernard intelligent electric actuator has archieved an excellent reputation over the years in this market thanks to a rangeof actuators providing the following features:Compact construction with a high output torqueSelf-locking gear train to maintain the position of the valve when the actuator is de-energizedVery good resistance to vibrationsVery simple settings - no specific tool requiredAdjustable mechanical travel limit stops to prevent overtravelRemovable drive socket for easy machiningEmergency handwheel and mechanical position indicator provided on all actuators as a standardMain featuresTransmission gears• The gear drive system is composed of 2 reduction stages:The first stage, driven directly by a pinion on the motor drive shaft, is a planetary system.The second stage, driven by the satellite wheels of the planetary gear consists of a worm and wheel gear type.•Since the planetary system permits a high speed reduction with an excellent efficiency, the subsequent gear is driven at a relatively low speed which ensures a better overall efficiency than normal standard gear designs.Position indicator• A visual position indicator allows a clear indication of the current valve position. 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 «lose on torque».Asynchronos 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.
