Rotary Air Lock Valve :
Fourteckh Enviro (India) Private Limited is a premier manufacturer, supplier, and exporter of high-precision Rotary Airlock Valves. Engineered for reliability, our RAVs are critical components for maintaining system pressure while facilitating the continuous discharge of bulk solids, dust, and powders.
The Core Function :
In transfer systems, pneumatic conveying and dust collection systems (such as Bag Filters, Cyclones, Multicyclones, Feeder, Silos), maintaining a pressure seal is vital. Our Rotary Airlock Valves act as the "air seal" between differential pressure zones. By maintaining a precision-engineered gap between the rotor and stator, the RAV prevents air leakage into negative-pressure systems, ensuring that gravity-fed material discharges efficiently without backflow.
Key Technical Features :
- Precision Engineering : We maintain a rigorous radial and axial clearance of 0.1 mm to 0.3 mm, ensuring minimal air leakage and maximum volumetric efficiency.
- Heavy-Duty Rotor Design : Equipped with 6 or 8-vane rotors welded to a high-tensile shaft for balanced rotation and structural integrity.
- Robust Housing (Stator) : Cast or fabricated housings designed to withstand abrasive materials and high-pressure differentials.
- Outboard Bearing Design : Bearings are mounted externally to protect them from heat and dust contamination, significantly extending the service life.
- Drive System : Powered by high-efficiency Geared Motors, customizable to specific RPM requirements for controlled discharge rates.
- Material Versatility : Available in Cast Iron, Stainless Steel (SS304/SS316), and Mild Steel to suit various corrosive or food-grade environments.
Specialized Configurations :
We offer three primary designs tailored to your specific material handling needs :
- Drop-Through : Standard gravity discharge applications. Best for General dust collection & granules.
- Side Entry : Designed for fragile materials to prevent "shearing.". Best for Large pellets or breakable solids.
- Blow-Through : Integrated directly into pneumatic conveying lines. Best for Fine powders requiring high-velocity transport.
- Shaft sealing : The same shall be with gland packing, labyrinth seal, mechanical seal depending on specific application and customer requirements.
- Rotor Blades Tips : Replaceable / adjustable tips with Spring Steel or SS.
- Quick Release / Opening Facility : to clean up the internals of RAV especially for food grade powder products.
Industry Applications :
- Agriculture : Grains, seeds, and pulses.
- Construction : Cement, sand, gravel, and crushed stone.
- Energy : Coal and biomass handling for power plants.
- Process Industries : Fertilizers, chemicals, and pharmaceutical powders, Rock phosphates
- Steel and Mining : In steel, metallurgical, mining, DIP, Sand
