Rotary valves are designed for use in all industrial areas in which powdery bulk materials are processed, conveyed, stored, distributed, weighed or metered. The MÖLLER® rotary valve is the right choice if you would like to have a controlled discharge out of the silo or hopper or if you would like to have a controlled feeding to a jet conveyor.

Typical bulk materials are fly ash, alumina, cement, lime, gypsum, minerals like copper concentrate etc. with a density from 0.5 to 2.0 t/m³.

The MÖLLER rotary valve is available from size 15 to 63. Depending on the bulk density it is possible to obtain a through-put  from 1 up to 100 m³/h.

The IP55 gear motor with the chain drive system ensures high operational reliability and is also available with a frequency converter.

Depending on the application the operating line pressure is up to 0.5 bar. The MÖLLER rotary valve is also available with a hopper with venting socket (see picture below for details of a typical pneumatic conveying application).


With the solution for 3 year maintenance-free operation you do not need to worry if the equipment is properly lubricated. The long-lasting lubrication ensures high performance over a long period. The improved seals, bearings, gearbox oil and chain secures that there is no maintenance required for a period of 3 years!
