DGX Premium Long Neck Typical 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 valve modular plug and dip tube are included.
The DGX Premium Typical 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.
Note that port plugs used on the modular valve with the typical side handwheel are notched on the corners of the wrench flats. The notches indicate the screw threads are reversed, and must be rotated clockwise to remove and rotated counter-clockwise to install. This is the opposite of typical screw threads and attempting to remove the notched plug using counter-clockwise force will permanently damage the valve.
This item is 100% what I expected! very good quality, it comes with everything you need dip tube, o-ring etc. All you need to do is attach the dip tube and it’s ready to be installed on your tank.
i purchased the left and right valves. This is actually my third set and the previous two sets have worked flawlessly through hundreds of fills so far. I personally use them for side mount, and I believe they work great for that application.
I bought my first pair of these valves a while back for a set of doubles. I've been so happy with them that I replaced all the short-neck valves on my sidemount bottles with these beauties.
1) These valves have a squared off base that makes it easy for my local technician to safely remove and re-torque them back into the cylinder. A lot of valves are rounded, not leaving a lot of safe places for a wrench to be mounted.
2) The beautiful satin finish has held up to a few overhead bumps and a couple of run-ins with gravel bottoms.
3) While I do rinse my valves after each day of diving, I have not been experiencing the usual corrosive build-up in the threads.
Once again, DGX is delivering another great product at a very competitive price.
