Abstract: Exemplary illustrations of a fluid valve, e.g., a return valve for returning residual paint, rinsing agent, and compressed air from a paint line when changing color in a painting system, are disclosed. An exemplary fluid valve may be adjusted between an open position, in which the fluid valve is at least partially open, e.g., for rinsing a paint line with a rinsing agent and for pressurizing the paint line with a new color for the color change, and a closed position, in which the fluid valve is closed, e.g., for applying the new color after the color change. An exemplary fluid valve may switch to the closed position, upon actuation by the medium thereof, e.g., medium flowing through or present in the valve. In another example, a fluid valve may close depending on the fluid present at the input side.
