What is AK valve scuba?
“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 Din in scuba?
The DIN is a threaded valve, wherein you screw the regulator into the tank valve. On the yoke valve, the main O-ring that seals the tank valve to the regulator first stage is placed on the tank valve. On the DIN, it is placed on the regulator first stage.
