Whats the differnce between a YOKE and DIN valve and which one is the most universal vale to choose when purchasing a regulator. I appologize for my ignorance. Its been a couple years since I was certified. I know one is more universal. I live in the US and want to use my equip on trips all over the world and the US.
The DIN valve is used for high-pressure steel tanks. The other style, the yoke or K-valve is for aluminum tanks and 3000 lb. steel tanks. The K-valve style is by far the most common. If and when you travel out of the states to dive, you will probably need the K-valve style first-stage--I don't think you can rent high-pressure tanks in most other places out of the U.S. One possibility is-if you use a DIN valve-you could purchase an adapter to convert over to the K-valve when you needed, that way you would have the best of both worlds without having to go to the dive shop to have your first-stage converted back and forth.
