Rotary Air Lock Valve (RAV) is the equipment which id fitted below the bag filter, cyclone, multiclone etc.

The mail function of the RAV is to lock the air and discharge the dust /powder. In the bag filter system there is negative pressure in the bag filter. So at the powder discharge point if there is any air leakage the powder will not fall down. So to restrict the sir leakage we provide the rotary air lock valve.
RAV consists of a stator & rotor. The radial $ axial clearance between is 0.1 to 0.3mm. The rotor has vanes (6 or 8) welded on the shaft. The rotor is mounted on the bearings at both the ends of the stator.
A geared motor is provided to rotate the rotor. Since the clearance between rotor & stator is so low the air leak is very minimum and it delivers only powder.

Rotay Air Lock Valve or RAV is the major component in any industrial processing equipment. It primarily acts as a tight seal to lock air between the inlet and outlet ports. On one side it locks the air and on the other, to makes the material move in a continuous rotation motion through its pockets. All these air lock valves are manufactured keeping in mind different aspects in an industrial processing including temperature and pressure. We can also customize these airlock valves according to the application requirements as to ensure accurate metering, feeding and control of materials.
