Rotary air lock are used to extract material from bins or silos which are under vacuum or pressurized. It extracts the material from the bin or silo without disturbing the vacuum or pressure of the system. Various options are available for different types of applications. Shown here is a flow through type of rotary air lock suitable for pneumatic conveying, delivering a controlled flow of material for conveying to pipes.

These are extensively used to discharge dust particles from cyclomax hopper/ bag filter. Our lock valves maintain the operating pressure in the system. These valves are also available in variety of sizes and capacities as required by our clients. The salient features and specifications are as follow: • service temperature: 100°c, 250°c, 400°c • differential pressure: 1500 mm wg (theoretical) • drive arrangement: chain drive, direct drive • rotor types: fixed rotor (c. I. ) • adjustable tip rotor (fabricated).

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. more...

The rotatory air lock feeders have multiple blade design to ensure best performance. Features adjustable tips for close rotor-to-housing clearances, peak valve efficiency and maximum life. The tips are manufactured in brass, stainless steel, abrasion-resistant steel, stellite inlaid, and Ni-hard.

We offer superior quality rotary air locks, which are reliable, efficient and have a long service life. An important key to rotary valve performance and durability is optimal selection of air lock, depending on your process requirements. Our long experience in selection, designing and manufacturing of rotary valves enables us to offer unmatched custom designs in the industry. Whether your requirement is heavy duty, drop-through, pneumatic, metering or simply emptying a dust collector, we can always provide you with a right valve for that.
Function Of rotary air lock : Multiple application feeding device helps to lock/determine the quantum of system air loss because of its precision complete. The application varies from ordinary volumetric feeder to a precise air locking device whenever the differential pressure varies. Rotary air locks are available in the size range of 150mm to desired size. Different designs are more...

Air Locks and Feeders are usually used to accomplish 3 basic tasks. To feed material from bins or hoppers. To deliver fines from the collector while sealing against air loss. And to feed material to pneumatic conveying line against pressure
