and patented by Walz & Krenzer in the 1960's, the conveyor belt
watertight bulkhead door uses simple pneumatic and hydraulic operation,
incorporating a unique rotating section between the upper trough
belt and the return belt. This ensures generous vertical and side
clearance, thereby eliminating belt and sealing gasket damage. Custom
designed for each application, these doors assure watertight integrity
for subdivision bulkheads.
Our design features automatically actuated, self-aligning plugs to accommodate
belt drift and assures positive sealing. These doors, proven through decades
of satisfactory service, are available for belt widths up to 120".
