A functional valve is an essential piece of dive equipment for any diver, as your air cylinder is more or less useless without one.
When dealing with scuba cylinders, high pressure valves are fitted onto the neck to control the gas flow. These valves also work as a connection point for the regulators.
Scuba valves are usually made of brass, with a layer of chrome plating.
At The Purple Octopus, we offer high functioning valves from well renowned brands like SanoSub and Aquatec.
