"IMPROVEMENTS IN OR RELATING TO VALVES" Abstract of the disclosure The invention provides a valve for dispensing material from a hopper. The valve comprises a body defining a passage way, a generally L-shaped valve member pivotally mounted to one side of the passageway such that the inner faces of the arms of the valve member can engage respective ones of a pair of spaced back to back valve seats disposed in the passageway so that in use with the downstream of the two arms closing the passageway by engaging the downstream valve seat a charge of material in the hopper can be received between the two arms and dispensed when the valve member is rotated to open the passageway by the downstream arm and subsequently close it by the upstream arm engaging the upstream valve seat; flow through the passageway being substantially obstructed by the upstream arm as the valve member is returned to close the passageway by the downstream arm.
