Elastomer–coated discs ensure the butterfly valves create a perfect seal at the passage point. In many application areas, however, sealing can be dispensed with. CK–M butterfly valves are a recent advance, where the valve has a metal seal, making them product–safe but not gas–tight. Such valves are primarily used as aspiration and control valves in suction pipes and exhaust piping. Even these particularly cost–effective valves are required to meet the usual Ebro standards of manufacturing quality and longevity.

Even Product Flow

Rotating impeller valves are used to regulate the flow of bulk goods to ensure an evenly paced discharge of material from silos, bulk containers, weighing tanks, mixers, etc. By controlling the speed of rotation, these impeller valves work as a volume–based dosing mechanism and also prevent downstream processes from being flooded with material. For instance, spiral conveyors or vibrating feeders are consistently supplied with the optimal amount of product, without any risk of clogging or compaction.

Valves for Rapid Flowing Bulks

For rapid–flowing goods, a pair of impeller valves interrupts the product stream at brief, regularly timed intervals, which effectively prevents any products from overshooting the mark. When the impeller valve is used in pneumatic conveyor systems, it regulates the output stream. Yet the installed height of the impeller is only about the same as that of a standard butterfly valve. Therefore, the impeller valves can be retrofitted to existing systems without the need for any major adjustments. Pipe sections also remain cylindrical, so there is no need to switch to square flanges.
