ABSTRACT:
A pivotal valve (10) for use in removal of catalysts (40) from reactors (30) having outer and inner flange plates (110, 120) with a plurality of spacers (130, 132, 134) firmly attached therebetween to form open regions (300, 302) between the spacers and the flange plates to allow free passage of the catalyst material (40) upon closure of the valve (10) to prevent jamming of the valve (10), a gate (140) pivotally attached between the plates (110, 120) for selectively opening and closing the nozzle hole (25) on the reactor nozzle (20) and an arcuate steel plate (190) on the pivotal gate (140) for selectively engaging the inner flange plate (120) next to the nozzle (20) to provide a complete circular seal around the nozzle hole (25) when the circular gate (140) is in the closed position.
