Stainless Steel Rotary Airlock Valve is also known as stainless steel rotary feeder,star discharger or rotary airlock.It is manufactured entirely of high-quality stainless steel materials,designed for corrosion resistance,hygiene,airtight sealing and quantitative discharging.

It is widely used for conveying and discharging powder,granular and pellet materials in food processing,pharmaceutical,chemical,environmental protection and new energy industries.The valve can maintain stable pressure difference in positive and negative pressure pneumatic conveying systems,effectively lock air,prevent air backflow,and realize continuous uniform feeding and discharging.

Main Features

Full Stainless Steel Construction

Adopt SS304/SS316L stainless steel body,rotor and cover plate,rust-proof,acid and alkali resistant,suitable for humid and corrosive working conditions.

Food Grade Hygienic Design

Smooth internal surface,no dead angle,easy to clean and sterilize,complies with food and pharmaceutical production hygiene standards.

Excellent Airtight Performance

Precision machined rotor and housing clearance,matched with high-quality shaft end seals,effectively isolate upstream and downstream air pressure,reduce air leakage rate.

Stable&Adjustable Feeding

Equipped with speed regulating motor,rotary speed adjustable,accurate metering,stable material discharge without blocking.

Durable&Low Maintenance

Integral casting or plate welding structure,high mechanical strength,wear-resistant and long service life,simple structure for easy disassembly and maintenance.

Working Principle

Material falls into the rotor blade cavity from the inlet by gravity.The motor drives the rotor to rotate at a constant speed,carrying materials to the outlet and discharging them continuously.Meanwhile,the rotor blades form an air isolation layer to lock air pressure,ensure the normal operation of pneumatic conveying and dust removal system.
