A valve, comprising:
- (a) a valve housing enclosing a flush plate;
- (b) the valve housing comprising a first opening and a second smaller vent opening;
- (c) the flush plate comprising a half-moon shape, a first opening, a second smaller vent opening, and an axis of rotation,
- wherein rotation of the flush plate with respect to the axis of rotation either (i) closes the first and second openings of the housing, (ii) allows the first opening of the housing to be open by aligning the first opening of the housing with the first opening of the flush plate, or (iii) allows the second opening of the housing to be open by aligning the second smaller vent opening of the housing with the second smaller vent opening of the flush plate, such that
- wherein the flush plate prevents both the first and second openings of the housing from being simultaneously open.

A valve for use on a vacuum toilet that cooperates with a waste tank under vacuum, the valve comprising:
- (a) a valve housing enclosing a flush plate;
- (b) the valve housing comprising a first opening and a second smaller vent opening;
- (c) the flush plate comprising a half-moon shape, a first opening, a second smaller vent opening, and an axis of rotation,
- wherein rotation of the flush plate with respect to the axis of rotation either (i) closes the first and second openings of the housing, (ii) allows the first opening of the housing to be open by aligning the first opening of the housing with the first opening of the flush plate, or (iii) allows the second opening of the housing to be open by aligning the second smaller vent opening of the housing with the second smaller vent opening of the flush plate, such that the waste tank is exposed to vacuum through the second smaller vent opening without evacuating waste from the vacuum toilet,
- wherein the flush plate prevents both the first and second openings of the housing from being simultaneously open.
