DMN-WESTINGHOUSE has designed The AL and AXL rotary valves for many applications in the metering and pneumatic conveying of products in powder and granular form. Due to the modular design of this extensive and flexible range of valves many configurations are available, using standard components. The AXL valves are supplied with a larger inlet in relation to rotor volume. They are specifically designed for applications where inlet size is more important than capacity or for handling products with poor flowability. The AL and AXL valve range includes USDA Dairy Accepted models and versions conforming to the EC 1935/2004 directive for sanitary use in the food and pharmaceutical industry. These stainless steel valves are easily detachable within minutes and meet the highest hygienic standards. The AL valves are also available with an optional body having one round and one square flange and a larger diameter inlet: the AML version. The AML valves can also be used as a transition piece from round to square or vice versa. Both AL and AXL standard and Dairy valves are optionally available in MZC execution with slide rails for easy removal of the end cover and rotor without damaging the housing. The AL valves are available in 10 consecutive sizes from 100-500mm (4"-20"), covering a capacity range of the rotor from 0.8-230 litre per revolution at 100% filling. In the 400-500 sizes the valves can also be supplied with square in- and outlet (type OS). The AXL valves are available in 4 sizes from 200- 350, capacity range of the rotor from 5.5-34 litre per revolution at 100% filling. The AXL size corresponds with the dimension of the inlet flange.
