Product Description
Basic functions 

Rotary airlock valve is a compact mechanical device for continuously discharging bulk powders or granules under gravity flow. By definition it is the simplest of machines having only one moving part (ignoring the drive); a multi-vane rotor revolving in close contact in the housing and where the housing has an inlet at the top, and an outlet at the bottom.

Despite its simplicity it offers several functional uses:

* Control product flow rate to the required rate (fixed or variable)

* Maintain a gas pressure differential between the inlet & outlet (airlock)

* Act as an explosion barrier

* Act as a Flame Barrier

* Act as a process isolator / barrier

Self cleaning rotary valve are suitable for dust-shaped and fine-grained bulk materials. If the bulk material tends to stick, this lock type is recommended for reasons of safety. The chambers are force-emptied with scrapers additionally. Cell wheels and housings are produced for precise sizes to be as tight as possible.Cleaning openings installed by default ensure quick, easy cleaning. Like all  airlocks, the bearings here were not integrated into the bearing plates either, but placed offset from them.


Ensures the trouble-free operation of the system when handling bulk solids having a tendency to stick, form coats and clot.

• Prevents expensive system standstills (e.g. cleaning) and production failures.

• Can be adapted to the prescribed or existing cross-section openings

• Can also be retrofitted if conventional rotary valves have failed


* Environment industry   *Metallurgy industry   *Chemical industry *Food industry * Grain industry     * Other industries


• For poorly flowing, humid products

• When vapours coming up from downside

• Rounded chambers

• Forced scraper; counter-rotating with respect to the rotor; ensure complete emptying of the chambers

• Common drive for the rotor and the scraper using synchromesh gears

• External bearing

• Pressure-shock-resistant up to 10 bar

• Sizes: from 200 x 200 mm to 500 x 800 mm

• Capacity range: 2 - 200 m³/h

Design Details

Something a little different- a rotary valve with a scraper unit for sticky materials. The valve is based on our standard MV 500 rotary valve but the rotor is a custom made unit with specially scalloped pockets. The geometry is carefully designed to that a simple scraper, powered by synchronised gears on the end opposite the motor.
For every 1/6 rotation, the scraper pulls any stuck material out of the bottom of the pocket to fall out of the valve and onwards into the process.
This particular unit has been designed for oily sunflower husks but it can be used for any product where a sticky residue builds up in the rotor.
