Aerodyne’s GatorGate double-dump valve can be used to discharge chunky, fibrous and abrasive material efficiently from dust collection systems. The valve works with low-pressure air or gravity-fed systems where standard rotary valves are prone to failure. The double-dump gate valve has a cam-operated drive mechanism and spring-loaded gates that open and close alternately, preventing air seepage and maintaining proper pressure.
