Rotary Air Lock Valve are important components of pneumatic conveying systems. Rotary airlock is also known as rotary valve, rotary feeder or airlock feeder. The basic use of the rotary airlock valve is as an airlock or sealing pressurized systems against loss of air or gas while maintaining a flow of material between components with different pressure. We Manufacture Rotary Air Locks used for feeding materials under vacuum or pressure while sealing in air & gas. Principle of gravity is used for dropping the material in the container. This is done with the help a vane rotor. The rotor consists of a no of Vanes and is available in different diameters as per the requirement of the process. The rotary air lock consists of rotor with minimum clearance of 0.5mm between van tip & interior of body. This is done to ensure perfect air locking considering the wear & tear of the rotors are driven with the help of standard motor & gearboxes. Our Rotary Air Lock Valves have high filling efficiency due to effective inlet shape and close running clearances. Our Rotary Airlock valves have wide application in industry wherever dry free-flowing powders, granules, crystals, or pellets are used. Typical materials include: Chemicals, Dyes, minerals, grains, plastics, dust, fly ash, flour, gypsum, lime, coffee, cereals, pharmaceuticals, etc. Application Areas

• Silo Discharge : The rotary valve placed under the silo or dust collection system is used to control the bulk solid discharge.
• Dosage Control : By controlling the rotation speed of the airlock feeder, volumetric metering and dosing of granular solids is achieved.
• Pneumatic Transportation : The airlock mounted under a cyclone is used for discharging the cyclone. Rotary valves mounted under cyclones, silos or hoppers are used to feed the pneumatic conveying line.
