Just received some of these new red inflation and deflation valves, and I’m curious as to how well the deflation valves hold. I originally got these for dump valves on the reserve air bags in the tubes, but am thinking now of adding them to the main seats in the rafts and my new sleeping mat (rather than just holding the inflation valve open). On the shop page it says they hold your weight standing on the test bag, but I’m wondering what happens if you give it a bit of abuse. If you “fall” or sit heavily, do they stay closed? I have an Exped deflation valve here, and it seems much harder to push the red one open with my finger than the Exped one, so I’m guessing that they probably will stand abuse.

Hi Lyn,
The manufacturer doesn’t indicate a pressure rating so I can’t guarantee anything, but I’ve tested them up to about 5 psi (350 hPa) myself and they showed no signs of stress.
For reference, a 170 lb (77 kg) weight distributed over an area of 12 x 18″ (30 x 45 cm) on an inflatable seat exerts about 0.8 psi (55 hPa) – quite a large safety factor.

Hi Josh,
Sure, I’ll try to get that done today. You can see a couple pictures of it in a packraft here, but I’ll take some pictures of just the seat as well.
Cheers,
Matt
