Abstract
A valve used in a sewage handling system allows outer casing components to be disconnected from each other while both of the fluid transporting or retaining components that are connected to the valve remain sealed from the environment when the valve is in a closed position. Yet, the valve can be operated by simple rotation of a single actuator. For example, the valve connects a conduit connected to a toilet with a sewage holding tank. The valve includes first and second connecting parts of an outer casing which are circular cross section housed cylinders with one end perpendicular to the axis of elongation of the cylinder and the second end forming an oval face disposed at an angle of about 35.degree.-55.degree. to the axis of elongation. First and second inner valve components have the same basic shape as the outer casing parts so that when the first inner element is aligned with a first outer casing part, the valve is completely closed and may be disassembled, whereas when the inner and outer parts are out of phase 180.degree., the valve is completely open and allows sewage to flow from the conduit to the holding tank.
