A multiway fluid selector valve comprises a housing 14, a distributer member 10 having a multiplicity of ports 11 opening into the housing and having their outer ends connected by pipes to separate gas ducts (not shown), a first selector member 12 within the housing for connecting any specified number of ports to a common duct 27 and a second selector member 49 for connecting the ports of a specified group to separate individual ducts, one of which, 78, is shown in Fig. 1. The first selector comprises a rotary disc 12 carried by a shaft 15 and having " through " ports 13 common in number and spacing to the ports 11 in the distributer member 10. Slidably mounted in the selector 12 is a collector chamber 21 spring biased into engagement with the top face of the distributer member 10. The collector chamber 21 is arranged to cover four radially aligned ports in the distributer member 10 and is connected by a flexible pipe 23 to the lower end of an axially extending duct 24 in the shaft 15. The upper end of this duct communicates with a chamber 25 which is, in turn, connected by a flexible pipe 26 to a union 27 in the wall of the housing 14. By moving the selector 12 to the appropriate angular position any group of four radially aligned outlets may be connected to the union 27. The second selector 49 comprises a member, having four collector chambers 50 to 53 therein, which is mounted on a radial arm 48 attached to a hollow shaft 47. The member 49 is spring urged into contact with the upper face of the first selector 12. The ports 50 and 51 are connected to vertical ducts 55 and 56 respectively in the hollow shaft 47 by means of flexible pipes 57. The upper end of the duct 55 is connected by means of a flexible pipe 58 to an annular groove in a disc 60 arranged for rotation with the hollow shaft 47. The duct 56 is similarly connected to an annular groove 61 in the disc 60. The ports 52 and 53 are connected by flexible pipes 63 to annular grooves 64 and 65, respectively, in a further disc 66 secured to the hollow shaft 47. Interposed between the two discs 60 and 66 is a fixed disc 67. Four ducts 71 and 74 (72, 73 not being shown) in the disc 67 are arranged to lead one to each of the annular grooves in the discs 60 and 66 and each duct is connected by a flexible pipe to separate unions 76 to 79 in the casing 14, only union 78 being shown in Fig. 1. By moving the selector 49 to an appropriate angular position, any four radially aligned outlets may be connected to the unions 76 to 79. Both selectors are rotated in opposite directions by pneumatic actuators 33 and 80. The actuator 33 has a ratchet type engagement with the disc 31 which rotates the shaft 15 and hence the selector 12. The actuator 80 has a similar engagement with the disc 70 which is keyed to the hollow shaft 47 and thus rotates the second selector 49.
