[Also in Division F2] A pneumatic actuator for a semi-rotary shut-off valve has a housing 1 made of a thermosetting resin e.g. glass-reinforced polyester-resin, and an aluminium vane 7 with a steel-cored hub 6, leakage being minimized by a rubber lining 8, which may define a double wiper-seal at the outer edge, Figs. 3 and 4 (not shown). A spool-valve 11 controls the flow of compressed air through ducts 13. Metal caps 14 engage with stops 12. Alternatively, the housing is made of metal and lined internally with rubber and the vane is made of glass-reinforced polyester-resin.
