Since 1989 Mavi has delivered hundreds of Romav rotary valves for the the Latin American and African markets. The simple concept allows the controlled discharging of bulk materials from silos, deposits and bins or feeding pneumatic conveyors, screw conveyors and others.
With capacities up to 46 m3/h and 340 mm diameter, Romav rotary valves are the leading technology for this type of equipment made in Brazil.
