Double dump valves are designed for controlled discharging of large particle size or high-temperature materials from silos, bins, or hoppers in heavy-duty applications. They are also used for processes that do not require continuous material flow.

Double dump valves are comprised of a robust casing and two alternately activated flaps, one installed on top of the other. Use them to promote the flow of bulky or fibrous materials that might clog or damage other valves.

Double Dump Valves can also provide an airlock between material storage and discharge point when moving between differing air pressure levels.
