Double Flap Valves

UNICON provides a complete line of dump valves (also known as double dump valve, or double flap valves) suitable for air lock applications. Similar to the rotary airlock valve, the dump valve is used in pneumatic conveying systems, dust control equipment, and as volumetric feed-controls to maintain an even flow of material through processing systems. In a dump valve, however, the flow control is accomplished through two chambers.
