Drum Rotary Valves for the unloading of dry bulk

Rotary Valves

For the unloading of dry bulk "bag-in-box" and dedicated atmospheric bulk containers Gardner Denver developed a universal trailer mounted rotary valve system. You can either select a complete self contained unit which includes a separate diesel engine or electric drive or a system driven through the vehicle engine. The combination of a robust rotary valve with one of our efficient blowers/compressors ensures you a reliable and cost effective system to offload your dry bulk products safely in the shortest time.

Alternatively we offer you electrically driven mobile units for use on site including all necessary adaptors for dedicated atmospheric bulk containers.
