Tank Valves
HOW TO CHOOSE A TANK VALVE:
Types: A DIN valve requires the regulator to screw directly into the tank valve. This style is more popular in Europe and with technical divers. A yoke valve requires the regulator to fit over the top of the tank valve and then is held in place with a tightening screw. This style is more popular in North America and the Caribbean, especially with rental tanks. An International or Pro-Valve looks like a yoke style, but has also has an insert that can be removed with an allen key which then allows use with DIN regulators.
