"Vocabulary of the week English and French for people working in shut-off valves (industrial valves)".

We need understand "запорная арматура" = industrial valves, fittings. "Запорная арматура" specifically shut-off valves, but broader "трубопроводная арматура". We'll include general terms.

Let's craft answer. Need perhaps "Лексика недели" implies weekly vocabulary. We'll present a list.

Need be accurate. Let's compile:

• Valve / vanne (f) / robinet? In French "soupape" for valve, "vanne" for gate/valve in piping, "robinet" for tap. Industrial: "appareil de robinetterie" or "vanne". We'll use "vanne" for valve.

• Shut-off valve - запорный клапан/задвижка. French "vanne d'arrêt". English "shut-off valve, stop valve".

• Gate valve - задвижка (fully open/closed) - English "gate valve", French "vanne à opercule" or "vanne à guillotine"? Actually gate valve = "vanne à opercule" (parallel gate) or "vanne à coin" (wedge gate). Let's be precise: Gate valve = "vanne à opercule" (opercule = disc) or "vanne à coin". In industry, "gate valve" = "vanne à opercule" (or "vanne-vanne"?). Let's use "vanne à opercule" (wedge gate = "vanne à coin"). Good.

• Globe valve - вентиль (запорный с линейным перемещением) - English "globe valve", French "robinet à soupape" or "vanne à chapeau"? Actually French: "robinet à soupape" for globe valve? Let's verify. In French industrial valve terminology: "globe valve" = "robinet à soupape" (or "soupape d'arrêt"?). Another term: "vanne à soupape" is not common. "Robinet à soupape" is a "stop valve" with a screw-down non-rising stem. Use "robinet à soupape". Also "ventile" is not French. Better: "robinet à soupape" for globe valve.

• Ball valve - шаровой кран - English "ball valve", French "robinet à boisseau sphérique" or "vanne à bille"? Actually "ball valve" = "robinet à bille" commonly. Use "robinet à bille".

• Butterfly valve - дисковый затвор / поворотная заслонка - English "butterfly valve", French "vanne papillon" (or "papillon" alone). "vanne papillon" common.

• Plug valve - краны пробковые - "plug valve" = "robinet à boisseau conique" (tapered plug). Use "robinet à tournant" (cock) but "plug valve" = "robinet à boisseau".

• Check valve - обратный клапан - English "check valve" or "non-return valve", French "clapet anti-retour" (or "clapet de non-retour"). Use both.

• Needle valve - игольчатый клапан/вентиль - "needle valve" = "pointeau" (valve) or "robinet à pointeau". Use "robinet à pointeau".

• Diaphragm valve - мембранный клапан - "diaphragm valve" = "vanne à membrane" (or "robinet à membrane").

• Pinch valve - шланговый клапан (пережимной) - "pinch valve" = "vanne à pincement" or "soupape à membrane"? Actually "pinch valve" = "clapet à manchon" (sleeve valve) or "vanne à étranglement"? Better: "vanne à pincement" (pinch). Might be less common. We can include.

• Angle valve - угловой вентиль/клапан - "angle valve" = "robinet d'équerre" (or "vanne à angle"). Use "robinet à angle".

• Safety valve - предохранительный клапан - "safety valve" = "soupape de sûreté" (or "soupape de sécurité").

• Relief valve - перепускной/предохранительный клапан - "relief valve" = "soupape de surpression"? Actually "relief valve" = "soupape de décharge" or "soupape de service". For pressure relief: "soupape de décompression". Use "soupape de décharge" for relief valve.
