Camelbak Crux On/Off Valve

As indicated in the title, it is in no way a reservoir, but indeed a tap (or a valve)! It is so ambiguous that I had to contact "materiel vélo" who confirmed to me that, in principle, it was indeed the product represented in the photo, and not a reservoir... I ordered it to replace the original one that only worked for 2 years; yes, programmed obsolescence? So this one of the same origin should not differ from the other and I would certainly have to reorder another one in a couple of years. Fortunately, "materiel vélo" is there to procure it?
