ABSTRACT:
A diverter valve for bulk solids is disclosed. The valve has a single inlet and two or more outlets, preferable three. Two pivotal gate valves are used for three outlets so that one is open and two are closed. The valve includes a novel pivotal gate structure which includes a resilient planar component sandwiched between two rigid planar components. The resilient component engages the valve housing so as to avoid metal to metal contact. The invention also includes a seal bar on each side of the housing which presents a linear surface that is perpendicular to the plane of the gate structure so as to present a firm surface against which the gate structure seals. The seal bars for each gate structure are discontinuous so as to accommodate positioning of the other gate structure in a smooth non-deformed sealing relationship to the housing. Additional seal bars engage the top and sides of each gate structure when moved to a “closed” position.
