A valve for dispensing a preferably viscous fluid is adapted in connection with the dispensing operation to open under the action of a positive pressure in the fluid, produced e.g. by means of a pump (1), and to close by it- self when the positive pressure, and thus the dispensing operation, has ceased. The valve (2) has a channel (9) with an inlet and an outlet end (9a; 9b) and an axial di- rection of fluid flow (10). The channel (9) is defined by a body portion (11) of rigid material and a cover portion (12) of flexible material. The body portion (11) is formed with a groove (13) of substantially arcuate cross-section. The edges of the cover portion (12) extending in the di- rection of flow (10) are sealingly connected to the body portion (11). Towards the outlet end (9b), the cover por- tion conforms to the shape of the groove (13). The cover portion (12) is prestressed to sealingly engage the wall of the groove (13) with a certain engagement pressure.
