VLV-VL002K

Postby camivill » Thu Aug 16, 2012 9:21 pm

What is the real use of this?
Every system should have this on the reservoir? or it is not imperative?
How much expansion would the liquid have at, let's say 60 C? or less?
Thanks.

Really no use for it. It all comes down to where the PC is located in the room and the temp thats in the room. So if its cold their will be a lot more pressure, best thing to do is not screw the cap on really tight at least have some air in the loop so the pump can breathe. If you have to much pressure the loop with explode and their are a few cases on the forums about that.

What happens when you don't use proper fluids and get bacteria etc or have excessive corrosion occurring is pressure can build up and this valve will allow that pressure to be released.

Think of it this way, you eat/drink something and your tummy hurts like you need to burp, then you burp and the pain goes away. If you never burped your belly could rupture.

Thanks.
I have my rig for almost 2 years, the thing is that i started to have a leak in the reservoir. I had very high temps due to a bad set up and it was almost 60 sometimes. So i disasamble the RP-980Bk finding a crack. I asked in another topic what would be the cause, and i felt it was due to a lack of "breathing" on the system as I screwed the tip of the reservoir.

I didn't get any warning about that. So i see this valve and now i am asking myself... ahhhhh so we have pressure changes in the system... :-0

So i learnt my lesson and i dont seal the system completely or have the VLV on the top of reservoir.

If you don't seal it completely that will help promote bacterial growth. It will also increase the conductivity of the fluid in the computer meaning a leak is more severe. Water itself isn't actually conductive it is all the crap inside the water that is conductive, thus by letting things like dust and other contaminates into the fluid the conductivity increases. That is why the valve keeps the loop fully shut and only opens with excessive pressure in the loop. In theory a healthy loop will never build enough pressure to actually make it open.

Thanks.
Is there any discussion about how often the liquid should be changed?

It really doesn't need to be changed but it's better to change it once a year so you know that you won't have anything in the liquid. Better safe than sorry same with the tubing.
