A valve is presented which is capable of metering and dispensing a quantity of a thick liquid or slurry on a rapid production basis. The valve allows the slurry to move through it freely except for momentary interruption during the actual metering and dispensing cycle and thus the heavier or more solid components of the slurry do not tend to settle out nor collect in the valve as readily as they would otherwise. Also, the valve is simple to construct and maintain having but one moving part in the slurry which first rotates to close the valve to enclose an exact metered portion of the slurry and then translates to dispense it.
