Abstract
The apparatus and method of the invention provides for a flush valve for controlling the vacuum evacuation of waste from a receptacle. The flush valve comprises an inlet port for receiving the waste from the receptacle, an outlet port opposite the inlet port and in fluid communication therewith, a source of vacuum connected to the outlet port and a uniquely designed discharge disk disposed between the inlet and outlet ports for interrupting the flow of fluid therebetween. In the preferred embodiment the flush valve is integral with a latticed panel of the waste receptacle stand.
