"Plutontek's Rotary Airlock Valves are specially dsigned and Manufactured considering accurate flow of material from one chamber to another while maintaining a good airlock condition.

Rotary airlock valve are primarily used for discharge of bulk solid material from hoppers, bins, receivers and cyclones  into a pressure or vacuum-driven pneumatic conveying system.

Atmost care needs to be taken during manufacturing for attaining the best clearance between Rotor and Body.


We supply Rotary airlock valves in 4 types :

  • Drop through Type
  • Blow Through type
  • Side Entry type
  • Sanitary type"


At Plutontek, we have to consider all the given parameters to design the RAV and has to offer the optimum solution to customer in order to achieve economies in intial cost as well as running cost.

Our supplied Airlock Valves are used in handling Pulverized Coal, Cement, Fly Ash, Flour, Lime, Ore, Soya Straw, Wooden Chips, Grains, Minerals, High Abrasive material, Pneumatic Conveying applications


"Areas of application may be anything out of below but limited to :

  • Material Conveying systems.
  • Pneumatic Conveying Systems.
  • Air Pollution Systems, 
  • In the dust filtration field good airlock is essential on cyclone and bag filter
  • Dust suppression equipment.
  • Feeding granular or fine material.
  • Cement and abrasive material manufacturing industries.


Cement, Steel, Food, pharmaciticals, sugar, and fertilizer, Chemical, pulp and papers etc."


"We can supply Rotary airlock valves with different material of constructions (MOC) depending on application, pressure & temperature required, flow rate required, clearance required,etc as per below :

  • Cast iron as per IS 210 Grade FG-260
  • MS fabricated as per IS 2062
  • SS-304 / SS-316S
  • Ail hard
  • Hardox- 500 "


We can supply Rotary Airlocks with following different combinations :

  • Open End Rotor- Rotary Airlock Valve
  • Closed End Rotor- Rotary Airlock Valve
  • Fixed Blade - Rotary Airlock Valve
  • Adjustable tip - Rotary Airlock Valve


Clearances between the rotor and housing are generally in the range of 0.10mm - 0.15mm for the standard valve. Tight clearances allow minimal air escape through the valve. This way product can be transferred between areas of differing pressure or vacuum.
