The primary function of a rotary airlock valve is to regulate the flow from one chamber to another while maintaining a good airlock condition.
We manufacture airlock valves (in India) in M.S., S.S., C.I., AL, and cast alloy with sizes maximum up to 1200 mm and with tailor made flange types.

Drop through rotary valves – loading directly from top       side and conveying side at  bottom / below.
Blow through rotary valves – material fed by air from       side and conveyed along the path on other side or       bottom.
Self-cleaning type rotary valves – Tips of the valve gets       cleaned during each rotation
During manufacturing of the valves, we take utmost       care to maintain accuracy of blade clearance.

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.
Pneumatic Transportation:-Rotary valves mounted       under cyclones, silos or hoppers are  used to feed       the pneumatic conveying line.
