The rotary valve, alternatively termed the electric ash discharge valve, comprises three components: motor, tooth differential star reducer or pin-wheel cycloidal reducer, and rotary vane discharger. It features two series with 60 specifications available. Square flanges at inlet and outlet represent type A, while circular flanges designate type B. This discharge apparatus serves as primary equipment for dust collection in dust removal systems, air distribution, and material feeding applications, proving suitable for powdered and granular substances. It finds extensive application across environmental protection, metallurgy, chemical processing, grain handling, food production, and other industrial domains. The rotary valve may be mounted at the discharge opening of negative pressure dischargers. The valve’s upper section receives material expelled from the discharger. The rotating impeller fulfills dual functions of material conveyance and sealing, preventing air infiltration through the discharge opening during pneumatic transport operations and guaranteeing normal discharger material flow.

Characteristics of Rotary Valve

1. This equipment exhibits superior machining accuracy and incorporates degassing functionality. It functions as a quantitative feeding device for dry pulverizing and classification systems, serves as a discharge unit for separation systems, or operates within dry pressure-conveying and suction-conveying pneumatic transport systems;
2. Equipped with a pressure equilibrium mechanism, enabling application in both positive pressure and negative pressure transport systems;
3. Construction materials include cast iron, cast steel, stainless steel, titanium steel, among others, with flange configurations available in square or circular designs and additional structural variations to satisfy diverse user requirements;
4. Streamlined construction, attractive appearance, convenient operation;
5. Reliable performance, minimal noise generation;
6. Due to the bearing and gearbox positioning at a designated distance from the housing, high-temperature resistance and lubrication capabilities are substantially enhanced;
7. This apparatus suits continuous operation duty, permitting both forward and reverse directional operation.

Live Cases:

The illustration below demonstrates the rotary valve application with turnover containers, vacuum feeders, and non-standard silos. The rotary valve mounts at the discharge opening of the unloader operating under negative pressure. Its upper section receives material expelled from the unloader, with the rotating impeller performing material conveying functions while simultaneously providing sealing to prevent air infiltration through the discharge opening during pneumatic transport processes and guarantee normal unloader discharge operation.
