Frequently Ask Questions

A Drop Through Rotary Valve is a rotary feeder or airlock valve used for the controlled discharge of powders, granules and dry bulk materials. Material enters from the top and drops through rotating rotor pockets to the outlet.
It is called Drop Through because the material moves essentially straight from the upper inlet through the rotating pockets and drops out through the lower discharge.
Alis Valves is a Drop Through Rotary Valve manufacturer and supplier in India, offering rotary feeding and airlock solutions for cement, chemical, fly ash, mineral, food, pharmaceutical and other bulk-material handling applications.
Yes. A suitable drop-through rotary valve can be used as an airlock or feeder in pneumatic conveying systems, particularly where the conveying arrangement permits bottom discharge.
Material enters the valve through the inlet and fills the rotor pockets. As the rotor rotates, the pockets carry the material to the bottom outlet, where it is discharged continuously.
They are closely related, but the terms describe slightly different application concepts. A drop-through rotary valve emphasizes the material-flow arrangement, while a rotary airlock emphasizes pressure separation between the inlet and outlet. A drop-through design can therefore function as a rotary airlock when properly designed for differential-pressure service.
A Slide Gate Valve provides isolation by moving a gate across the flow passage. A Drop Through Rotary Valve provides continuous or controlled material feeding through rotating pockets. Therefore, a slide gate is primarily an isolation device, while a rotary valve is primarily a feeding/discharge device.
