Rotary valve / Blow-through valves

for many applications in dosing and pneumatic conveying

AL / BL

Rotary valves of the AL/BL series

Rotary valves are used for feeding products into pneumatic pressure (BL) or suction (AL) conveying systems and also for dosing tasks. Due to a modular structure, many configurations are available. The rotary valve program includes USDA Dairy Accepted models and versions that comply with the EC directive of 1935/2004 for hygienic use in the food and pharmaceutical industries. The rotary valves are available in 10 sizes from 100 to 500 mm and cover a performance range from 0.8 to 230 litres per revolution at 100% filling.

AMMAG system components are always designed and manufactured specifically for the application and for optimised operational safety and economic efficiency. Our rotary valves are FDA-compliant, available in ATEX design, with EN1935 / 2004 certificate and with a wide range of accessories.

Our Service:

Trials of pneumatic conveying in our pilot plant. That gives us both confidence, even with new products where there is no empirical data.

Our engineering and sales team supports you with knowledge and experience in all questions about bulk material technology, fluidised bed spray granulation, product development and process optimisation.
