DGX Premium Long Neck Left (Uncommon Side) valves are 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 standard 0.750-14 NPSM (3/4 NPS) neck threads for use with all modern aluminum and steel SCUBA tanks and include a threaded 'dip tube' with hex opening for easy installation. Valves have a 5250 psi burst disk. The modular plug and dip tube are included.

The DGX Premium uncommon side 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 handwheel is standard, and an optional green, red or blue color handwheel is available.
