Rotary valve
Review
A rotary valve serves as a crucial component for the continuous discharge of granular or powdered products in a system. Material from the filter hopper or auger flows into the valve's inlet and is then conveyed and discharged from its lower section. In dust collection systems and pneumatic conveying setups, the valve functions as an airlock, preventing air from entering connected equipment. Its design is both robust and compact, facilitating easy and swift access to internal mechanical parts, thus minimizing maintenance time significantly. Certified according to EN 15089 standards, the rotary valve is engineered to mitigate explosion propagation between equipment pieces as an added safety measure.

How the rotary valve works
The material is loaded into the rotary valve through the upper inlet, and the constantly rotating valve rotor moves the material to the lower part of the valve, where it is discharged through the external port.
Due to the minimal gap between the body and the rotor the valve does not allow air to pass through and reliably seals the process.
