Double Dump Valve

October 26, 2011
The GatorGate Double Dump Valve discharges material while maintaining a positive airlock seal through a pair of sequentially timed flap gates. The upper gate opens, allowing chunky, fibrous, or abrasive material to drop onto the closed lower gate. The upper gate then re-closes to maintain the airlock seal. The lower gate then opens to discharge material from the system. Unlike competing dump valves, the GatorGate from Aerodyne utilizes a unique cam-operated drive mechanism, according to the manufacturer. As the specially designed cam rotates, it actuates the upper and lower flap gates in sequence for a highly reliable and consistent airlock seal.
