Rotary Valve for Demanding Applications

December 2, 2013

Coperion K-Tron Maximum-Duty Aerolock Rotary ValveThe Coperion K-Tron Maximum-Duty (MD) Aerolock™ rotary valve is engineered for heavy to severe industrial service with pressure differentials up to 1.4 bar (20 PSI) and/or temperatures of 121 C (250 F). The unit is designed to withstand severe shock loads and elevated temperatures consistent with continuous 24-hour use. The MD is commonly used with some of the most challenging materials including minerals, chemicals, fillers, food ingredients, filled pellets, PVC compound and diatomaceous earth. The MD has a 10-blade rotor that maintains a minimum three-blade labyrinth seal to minimize air leakage. The 10-blade rotor is available with flat or relieved tips in several rotor choices including open-ended, hubbed, reduced displacement and staggered pocket. The MD utilizes two tapered roller bearings on both the thrust and drive sides. Materials of construction include carbon and stainless steel with multiple coating options.
