AML
The AML air lock has been designed by DMN-WESTINGHOUSE
for many applications in the metering and pneumatic
conveying of products in powder and granular form.
The AML valve can also be used as a transition piece from
round to square or vice versa.
An extensive and flexible range of rotary valves is available.
Due to the modular design of the valves many different
configurations are available, using standard components.
The product line also includes USDA approved models for
sanitary use in the food and pharmaceutical industry, the
types Dairy and Dairy MZC. These stainless steel valves
are easy detachable in a few minutes and meet the highest
hygienic standards.
The AML valves are available in 7 consecutive sizes from
100-400, covering a capacity range of the rotor from 0, 8 to
58 litre per revolution at 100 % filling.
Drive options include chain, direct, air and hydraulic drive.

Product information
The valves are available in two materials of construction:
cast iron and stainless steel.The cast iron valves are also
available nickel or chrome plated or tungsten coated.
