Frequently Ask Questions
A Blow Through Rotary Valve is a rotary airlock feeder designed to continuously feed powders and granules into a pneumatic conveying system while allowing conveying air to pass through the valve with the material.
It is called a Blow Through Rotary Valve because conveying air passes through the valve outlet and carries the material directly into the pneumatic conveying line.
Alis Valves is a Blow Through Rotary Valve manufacturer and supplier in India, offering rotary airlock and bulk-material handling solutions for pneumatic conveying, cement, chemical, mineral, fly ash and other powder-handling applications.
Material enters the rotor pockets from the inlet. The rotating rotor carries the material toward the outlet, where conveying air assists in blowing the material into the downstream pipeline.
They are closely related. A blow-through rotary valve is a specialized rotary airlock feeder designed specifically for applications where conveying air passes through the discharge side to transport the material.
