robinet

Another word that can often be used to translate 'robinet' is 'cock' — usually found with a qualifier. So we might have 'drain cock' (robinet de purge OR de vidange), 'stop-cock' (robinet OR vanne d'arrêt), etc.

Note that FR uses 'valve' as in EN for things like internal combustion engines, tyres, etc.

I think another clue may be the size — one clearly wouldn't have a 2' diameter 'tap' on a crude oil pipeline!! But here, it seems you are dealing with relatively small bores (¼"), where 'tap' seems eminently suitable in many cases. Of course, as has already been said, it may depend if it is hand operated or not: one might reasonably expect to turn a tap on or off by hand, whereas anything more industrial perhaps, requiring greater force, might tend towards the sense of 'valve'.

Since 'tap' can sound more like a lay-person's term, it might be felt out of place in some more technical contexts; conversely, 'valve' can be seen to have a more technical connotation and hence be out of place in an everyday situation — one would hardly say "turn on the kitchen valve to fill the kettle"!

I understand the problem you have here — and the trouble is, the way the termes 'robinet' and 'vanne' are used in FR is not exactly the same as the way the terms 'tap' and 'valve' are used in EN! Not leats because some writers use the terms completely interchangeably in FR, while others use the 2 different terms to make a specific distinction — and in both instances, you can't simply do the same in EN!

My purely instinctive feeling is that in EN-GB, the word 'tap' is often used for something that controls the output from a pipe or soemthing — this is the "everyday" meaning we are used to in 'a kitchen / bathroom / garden tap' etc. Then there is the (now slightly dates, perhaps) usage for things like a 'gas tap' — which does, after all, regulate the output of something, in a certain respect.

A 'tap' tends to presuppose soemthing about the form it will take, in a way that 'valave' doesn't — the latter really describes more what its function is: a 16-valve car / a non-return valve / a pressure-relieveing valve; in none of those examples could we possibly use 'tap' in EN!

Can you please describe the purpose of installation? this my give a clue for the valve type being used, probably.

No, I do not have any pictures.

Do you have pictures or descriptions of the "robinet" and it's manipulation?

Thanks!

I am enclosing the sentence before and after:
Monter l’électrovalve sur le support H15 (voir Schéma 97, page 260) et fixer la dans le dispositif de fixation universel H4 sur le côté gauche du banc d’essai
Connecter le raccord A2 à l’aide d’un flexible ¼“ à la fiche d’accouplement du robinet 13.
Connecter le raccord A3 à l’aide d’un flexible ¼“ à la fiche d’accouplement du robinet 7.

The context is the sentences before and after this one.
Here's an example of a well written question:

The reason I don't give much context is that there is not much context available. I only know that I am working on pressure valve testing equipment. Thank you for your comment.

Your last three questions have been almost entirely without context, which is why you're not getting much of a response. In one case, you gave a very laconic reply to a request for more information.
If you submit questions containing several sentences from before and after your word or phrase, and say what research you've done and what your thoughts are, people will be much more willing to help.
