A Rotary Airlock Valve (RAV) is a mechanical device in bulk material handling that controls the flow of powders, granules, and pellets from one system (like a silo or hopper) to another (like a pneumatic conveyor) while preventing air leakage, thus maintaining pressure differentials and system efficiency. It features a rotating rotor with pockets (vanes/blades) that trap material at the inlet, carry it through the housing, and release it at the outlet, acting as a precise feeder and airlock. 

An air vent valve (or automatic air vent, air release valve) is a crucial hydromechanical device in fluid systems that automatically releases trapped air or gases, preventing issues like reduced flow, water hammer, corrosion, and airlocks, ensuring efficient operation by expelling air through a float mechanism and admitting air during draining to prevent vacuum. 

A Rotary Airlock Valve (RAV) is a mechanical device in bulk material handling that controls the flow of powders, granules, or pellets from one chamber (like a hopper) to another (like a pneumatic conveyor) while preventing air leakage, acting like a revolving door for materials. Its rotating multi-vane rotor creates pockets that trap and transport material, minimizing pressure loss between system sections operating at different pressures (vacuum or pressure) for efficient operation in industrial processes.
