An apparatus for coating an optical fibre 42 with a selected one of a plurality of different resins 16, 18, 20 comprises respective reservoirs 10, 12, 14 for the resins, an applicator 40 for applying a resin coating to the optical fibre and a distribution means between the reservoirs and the applicator including a valve device 34 which is operable for putting any selected one of the reservoirs in flow communication with the applicator. The valve device comprises a first body 44 defining a plurality of inlet passages 28, 30, 32 each of which is interconnected to a respective reservoir 10, 12, 14 by a respective inlet conduit 22, 24, 26 and a second body 46 defining an outlet passage 36 which is interconnected to the applicator 40 via an outlet conduit 38. A flow control device 48 is disposed between the bodies 44 and 46 and the bodies are relatively moveable for putting any selected one of the inlet passages 28, 30, 32 in alignment with the outlet passage 36. The flow control device has a first position relative to the second body 46 for blocking all of the inlet passages and the outlet passage and a second position relative to the second body 46 for allowing flow to the outlet passage from an inlet passage aligned therewith.
