DMN-WESTINGHOUSE has designed the BL and BXL blow through 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 different configurations are available, using standard components. The BXL valve with enlarged inlet is specially designed for applications where inlet size is more important than capacity, or for handling products with poor flowability. This valve is also available with an extra enlarged inlet: type BXXL. The BL Dairy range includes USDA Dairy Accepted models and versions conforming to the EC 1934/2004 directive for sanitary use in the food and pharmaceutical industry. These stainless-steel valves are easily detachable in a few minutes and meet the highest hygienic standards. Both BL and BXL valves are optionally available in MZC execution with supporting rails for easy removal of the end cover and rotor without damaging the housing. The BL valves are available in 6 consecutive sizes from 150-350, rotor capacity ranging from 2,5-58 liter per revolution at 100% filling. The BXL valves are available in 4 sizes from 200-350, the capacity range of the rotor from 5,5-34 liter per revolution at 100% filling. The BXL size corresponds with the dimension of the inlet flange. The BXXL valve sizes are available upon request.
