Standard Duty Rotary Valves

The Standard Duty Rotary Valve is a less expensive alternative to the Heavy Duty Airlocks, and is ideal for applications where a more robust valve is not required.  The Standard Duty Rotary Valve is used in gravity flow or low-pressure differential applications such as on the bottom of a dust collector, surge hopper or silo, and are used for handling dry, free flowing, non-abrasive materials.  These units are precision machined for tight tolerances, as with all of our rotary airlocks, to insure minimal air leakage.  All standard duty rotary valves are cast iron with a mild steel closed end rotor.  Both round and square flange units are available in the following sizes:  6, 8, 10 and 12 inch.

 

 

Standard Duty Rotary Airlock Valves

The Standard Duty Drop Thru Rotary Airlock is a less expensive alternative to the Heavy Duty Airlocks and is ideal for applications where a more robust valve is not required.

The Standard Duty Airlock is used in gravity flow or low-pressure differential applications such as on the bottom of a dust collector, surge hopper or silo, and are used for handling dry, free flowing, non-abrasive materials.

These units are precision machined for tight tolerances, as with all of our rotary airlocks, to ensure minimal air leakage.

All standard duty airlocks are cast iron with a mild steel closed end rotor.  Both round and square flange units are available in the following sizes:  6, 8, 10 and 12 inches.

Sizes available:

  • 6, 8, 10 and 12 inch
  • Round or Square Flanges

Features & Benefits:

  • Heavy Duty Castings for Body and End Covers.
  • Closed-End Rotor with Fixed Vanes.
  • End covers are spigot located into the body for concentricity.
  • The body, end covers, and rotor are precisely machined in CNC center to ensure tight tolerances, minimal clearances between the rotor and housing, maximum pressure differential sealing, and minimal leakage.
  • Sealed for Life Ball Bearings.
  • Standard drives package includes right angle gearboxes mounted directly onto the rotor shaft. The gearbox will accommodate any C Flange motor whether it is TEFC, explosion proof, chemical duty, inverter duty, wash down duty, etc.
  • Compact assembled units deliver ready to be installed.
  • Wide range of sizes available from stock for quick shipment.
  • Economical

Options:

Standard Duty Airlocks have two main functions:

  • Feeder applications with no pressure used purely to feed product from a bin or hopper at a controlled rate.
  • Filter applications e.g. cyclones, baghouses and various collectors where fine dust must be collected while maintaining an air seal.
