Engineering Overview & Design Highlights
The JMEF Rotary Air Lock Valve (also known as Rotary Feeder or Star Valve) is an essential component in dust collection, pneumatic conveying, and cyclone discharge systems. Manufactured with precision CNC machining in Vatva GIDC, our valves maintain a continuous pressure air-seal while steadily discharging bulk powders.
Working Principle & Mechanical Operation
A multi-pocket precision-machined rotor rotates inside a heavy cylindrical casing. Material falls into the upper pockets from a cyclone or silo. As the rotor turns, the material is discharged through the bottom port while the close-tolerance rotor vanes prevent air leakage between differing pressure zones.
Salient Features & Technical Advantages
-
Precision rotor-to-body clearance of 0.08 mm to 0.12 mm ensuring minimal air leakage.
-
8-pocket or 10-pocket rotor design for continuous, non-pulsating volumetric discharge.
-
External outrigger bearing design protecting bearings from product contamination and high temperatures.
-
Available with adjustable polyurethane or brass tips for handling fibrous or sticky products.
