RK Engineering is a premier Rotary Air Lock Valve manufacturer, supplier, and exporter specializing in precision-engineered air seal solutions. Based in Vatva, Ahmedabad, we design heavy-duty Rotary Air Lock Valves (also known as Rotary Feeders) that are essential for maintaining a consistent pressure seal while regulating the flow of bulk solids, powders, and granules. Our valves are the “gatekeepers” of pneumatic conveying systems, dust collectors, and cyclone separators, ensuring 100% airtight performance and preventing pressure loss in high-demand industrial environments.

As a globally trusted Rotary Air Lock Valve exporter, we deliver world-class engineering to major industrial sectors in Kenya, South Africa, Canada, and the USA. Our valves are manufactured using high-grade Stainless Steel (SS 304/316) and Cast Iron to withstand abrasive materials and high-temperature conditions. Whether you need a valve for a Bag Filter, Cyclone, or Spray Dryer, our designs focus on precision clearances and rugged durability, ensuring a clean, efficient, and dust-free factory operation.

Pressure Management: Maintains a perfect air seal between different pressure zones in pneumatic conveying.
Non-Clogging Design: Precision-machined rotors with variable speed feeders ensure smooth material discharge without blockages.
Explosion Protection: Acts as a flame barrier to prevent dust explosions from traveling through the system.
Versatile Applications: Widely used in the Chemical, Food Processing, Pharmaceutical, Cement, and Mineral industries across Canada and the USA.
Low Maintenance: Heavy-duty bearings and robust housing ensure long service life with minimal downtime.
The primary function is to act as an "air seal" while continuously discharging bulk solids (powders, granules, pellets). It maintains a specific pressure differential between two zones, ensuring 100% airtight performance.
We maintain high-precision tip clearances (< 0.20 mm) between the rotor and the housing. Additionally, we use 8-blade or 10-blade rotors and specialized gland packing to minimize air bypass.
Yes. Our standard valves handle up to 250°C, while High-Temperature Rotary Feeders with outboard bearings and heat-resistant seals can operate efficiently up to 400°C.
Yes. We offer VFD-compatible gear motors (0.5 HP to 5 HP) to precisely control the discharge rate (RPM) based on your production requirements.
Absolutely. We supply motors and control panels configured for 60Hz frequency and specific voltage requirements (e.g., 460V), ensuring "plug-and-play" compatibility.
We provide heavy-duty, reinforced valves for rugged environments in mining and agriculture sectors. All exports include sea-worthy packaging and full technical documentation.
