DGX Premium Valves Nitrox Ready, using oxygen compatible materials and when sealed in the original factory packaging is also free of organic and particle contamination. The valves have DIN outlets that can accept optional removable inserts (sold separately) so the valves may be used with yoke connectors. You may see this style of outlet variously described as Pro, 200-Bar DIN (G 5/8 BSP), or 232-Bar DIN. All these different names apply to exactly the same style valve outlet, which is suitable for use with the 3442 psi service pressure cylinders and any DIN style regulator or (with the addition of an optional insert) converted for any yoke style regulator. Inlets have imperial 0.750-14 NPSM (3/4 NPS) neck threads for use with modern aluminum and steel SCUBA tanks manufactured for the North American market. Inlets also include a threaded 'dip tube' with hex opening suitable for easy dependable installation with a hex key. Valves have a 5250 psi burst disk.
The DGX Premium valves include a nearly indestructible handwheel made from soft rubber formed around a stainless steel insert. The stainless steel insert ensures positive operation with long-lasting life. The large ribs make it easy to open or close the valve even while wearing gloves. The rubber with stainless steel insert handwheel design is the preferred choice of technical divers. The black color handwheel is standard, and several optional handwheel colors are available.
It keeps gas in when shut , it lets it out when open and even lets out a small amount when open a small amount but seriously, yeah it’s a pretty nice valve easy to grab to carry a tank with. The quality of the chrome job is good and they have the same style, simple to service insides as a san o sub valve that most of us would be very familiar with the insides of. Would be nice if it came with a DInsert but considering the great price on this and the fact you can order a DInsert for $4 no one is complaining.
