Rotary Discharge Valve

Angran has been producing rotary discharge valves since 2018. Our factory in Botou, Hebei, includes a skilled R&D team. Also known as a star feeder or airlock, this valve sits under the dust collector hopper. Its job is to discharge dust while maintaining an airtight seal, preventing outside air from entering the system.

Our latest model features excellent anti-clog performance, a stable seal, and wear-resistant construction for long life. You can use a variable frequency motor to control speed. Installation is simple, and it fits a wide range of dust collectors and storage bins. OEM services are supported. Minimum order: 1 piece. Non-worn parts carry a 1-year warranty.

We can customize flange sizes and discharge volumes for your specific application. For sticky materials, we add an anti-jamming design. Each valve is checked before packing, and third-party inspection is welcome. Our after-sales team confirms your hopper size before shipping.
