In the case of a valve for a hydraulic line with a valve housing (10) into which an adapter (12) is inserted with an inlet aperture (15), an outlet aperture and a non-return valve arranged between them for the hydraulic fluid, an intake device comprising a nozzle (72) and a diffusor (71) is arranged in the adapter (12), which intake device is connected to a metering device (78) for an additive to be fed into the hydraulic fluid located on the outside of the adapter (12). This arrangement makes it possible to draw any selectable quantity of an additive into the flow of hydraulic fluid. Such an additive may be a washing agent, for example. <IMAGE>
