A fitting for a thermostatic valve comprises a housing (1) with a bore (33) which receives a valve insert (11). The latter consists of a shank carrier (12) and a seating carrier (13), adjacent ends thereof being received within a union (4). An outer portion of the shank carrier (12) carries means (36) for securing a thermostat. The shank carrier (12) is secured to the union (4) and the seating carrier (13) comprises retaining means (24,29) within the union (4) for defining its axial position. The axial length of the bore (33) is preferably considerably longer than that of a sealing head (34) on an extension (32) of the seating carrier (13). The seating carrier (13) may be of brass or plastics, and may have a throttling bore. An adaptor may be provided, e.g. to fit on a screwthreaded formation (46) on the shank carrier, for receiving different types of thermostat. <IMAGE> |
