Gericke USA has unveiled its new line of rotary valves, RotaVal. This new line offers a choice of more than 15,000 different configurations to suit powder handling processes, along with custom valves for special situations.
Engineered for rugged performance in the food, dairy, chemical, pharmaceutical, plastics, mineral and other industries, the valves have been proven to safely discharge powders from hoppers, fill process machinery, dose from silos, and isolate pneumatic conveying zones between sifters, mixers, screw conveyors, and other equipment.
The valves feature stainless steel construction, and are available with hastelloy and other food-grade coatings as needed.
The heavy-duty series valves are offered in a choice of cast iron, SG iron, stainless steel, or aluminum to match the process requirements without over-specifying and come in standard sizes as large as 600 by 1200 mm. For highly abrasive materials and extreme situations, the extra heavy-duty valves feature durable cast iron with hardened steel blades, plasma nitride-coated shaft sleeves, and tungsten carbide-coated liners for high wear resistance. All of the valves are available in optional explosion containment models for processing combustible dust.
