Technical Specs


VDC Double Dump Valves consist of a robust casing and two alternately activated flaps, one installed on top of the other.
VDC Double Dump Valves are the ideal solution for controlled discharging of particularly high temperature or abrasive, large particle size materials. They are most suitable for discharging dust from large de-dusting units and for heavy-duty applications in general, in virtually all industries. They are also used for processes that do not require continuous material flow.
Double Dump Valves


VDC Double Dump Valves are designed to withstand high temperatures, for abrasive materials and those with irregular particle size in bulk solids handling processes in which constant material flow is important.
