Content: Turning the knob left (counterclockwise) would open the valve while turning it right (clockwise) would close it. O-Ring
Scuba valves typically have an O-ring that helps create a secure seal between the valve and the regulator. However, it can sometimes be on the regulator itself, depending on the connection or attachment method used (more on this below). Burst Disk
This thin copper disk is more of a safety feature that is designed to rupture once the tank’s internal pressure reaches a certain level, thus helping divers avoid serious bodily injuries. Snorkel
The valve snorkel is not what you wear but a tube that extends from the bottom of the valve and stops debris from flowing through it when the tank is inverted. Yoke vs DIN Fittings
Before we talk about the kinds of valves that are available on the market, let us describe the two ways in which the valve attaches your regulator to the tank. Yoke
Also referred to as the A-clamp or international fitting, the yoke was the standard connection for many tanks around the world. A yoke regulator connection features an oval metal brace that fits over the top of the tank valve. It also has a rotating black plastic handle that’s used to tighten the regulator’s metal yoke screw onto the tank valve. The O-ring, which is situated visibly on the yoke valve itself rather than on the regulator, expands by air pressure as it tries to create a seal between the valve and regulator.
