I already have a non-return ball valve, a non-return swing check valve but the 'obus' has defeated me. TIA to all.

"A feature of the nozzle check valve DRV-Z is its inherent non ?slam characteristic. This is attained because the valve reacts so quickly to flow (velocity) changes that it is always able to outpace the process change and be at the point of closure before it is possible to obtain reverse flow."

On the other hand, the illustration shows a valve rather different from the French one.

Core non-return valve


Explanation:
1) OK for "non return valve" = "clapet de non-retour".

2) "Obus de valve" = "valve core" (see Web ref 1).

Notes to answerer
Asker: Hi, thanks for your reply but I have difficulty in relating this to a gas pipeline. I know that it is a non-return valve, presumably similar to a ball valve, but nozzle check I'm not sure about.

Asker: Second attempt much more interesting ta muchly!!
