- (клапанного типа) — valve
- (усилителя "сопло-заслонка") — jet interrupter blade
-, аварийная (выключения турбины ппо) — (c.s.d. turbine) emergency air cut-out valve
- карбюратора, воздушная — carburettor choke valve
- кольцевания (системы кондиционирования воздуха) — pneumatic /air/ cross-feed valve (pneu x-feed vlv)
- маслорадиатора — oil cooler door

- отбора воздуха, распределительная (зов) — air bleed selector valve
- переключения подачи воздуха сверху-снизу (системы скв) — downflow-upflow air selector valve
-, перекрывная (общий термин) — shut-off /cut-out/ valve
-, перекрывная (возд. стартера) — engine
-, перекрывная (противообледенительного трубопровода подвода горячего воздуха) — anti-icing shut-off valve (antiice valve)
- подачи воздуха на запуск двигателя — engine start air valve
-, подпружиненная на закрытие (открытие) — valve spring-loaded into closed (open) position
