Rotary Airlock Valve

The rotary valve is a component for the continuous discharge of granular or powdery products coming from silos, hoppers, pneumatic conveying systems, filters, cyclones. The dusts coming from the filter hopper or from the screw, fall into the loading mouth of the valve, are conveyed, and subsequently unloaded in the lower part.


The rotary valve is designed according to a criterion of maximum applicative universality. The internal rotor rotates to allow continuous discharge between two environments at different pressures. Its construction is sturdy and compact, the access to internal mechanical parts is easy and fast.
