“K” valves are the simplest of all valves, and are found on most modern cylinders. These valves fit regulators with yoke attachments. The o-ring on a “K” valve is expanded by air pressure, and this expansion creates the seal between the regulator and valve.

What is in scuba tank air?

Why is helium used in scuba diving?
The main reason for adding helium to the breathing mix is to reduce the proportions of nitrogen and oxygen below those of air, to allow the gas mix to be breathed safely on deep dives. Helium has very little narcotic effect. A lower proportion of oxygen reduces the risk of oxygen toxicity on deep dives.
