DEMECH Slide Gate Valves are designed to provide a quick acting isolation valve unit that can be installed into a bulk handling flow path to stop material flow.

DEMECH slide gate valves are simple and compact in design, robust in structure, excellent in technology and are easy to install. Slide gate valves are designed to shut off product flow from outlets of storage bins, silos, conveyors, and other discharge points handling dry bulk materials.

Slide gate valves are required for isolating the bulk material collecting vessel in a bulk material handling system. The vessel could be hoppers, silos, bag filter or bins.
