Abstract: An improved bulk cement metering apparatus includes a valve housing having a cylindrical inner housing bore. The housing has an inlet opening through a side wall thereof. A housing outlet is defined at an open lower end of the cylindrical valve housing. A cylindrical valve element is concentrically and rotatably received within the housing bore.
