Heavy Duty Stopper Actuator for molten iron


The RACT is designed to fit almost any tap out application in the molten iron industry.
The mechanical parts and properties are very robust and the mounting is very flexible. There are many options like the possibility to rotate the rod and also an internal cleaning plunger to remove sludge. The drive system is available as either electrical or pneumatic. When used for filling molds in a fast operating line the drive system uses a servomotor system. RACT has been designed to work with the Precimeter ProV metal level sensor.
