Whether your system is handling bulk fine powders, plastic granules, abrasive or bulk solids, HUBLUXE valves are engineered to prevent air leakage and maximise the efficiency of dust collections, silos and cyclones.

Our gravity feed rotary valve design is specifically engineered for systems where material falls vertically into the rotor, making it the most efficient rotary airlock valve for dust collector and silo discharge applications.

Each standard drop through RAV features precision rotor clearances to minimize air leakage, which is critical for the performance of an industrial RAV for silo discharge in cement and chemical industries. Our rotary feeder valve gravity discharge design supports continuous operation.

Choosing a reliable drop through airlock manufacturer ensures your process maintains a high-pressure seal while facilitating a consistent discharge of powders and granules.

What is Drop through Rotary valve?

In drop through rotary valve, materials fall directly into the inlet of RAV and gets rotated by rotor (located in housing of RAV) to exit from outlet flange by gravity. It is an ideal solutions for handling dust collection, hoppers, silo, Cements, and bulk materials.
