DGX Premium Modular Valve, Right (Typical Side)

- Valves have a recessed 5250 psi burst disk
DGX Premium Modular Valve (Typical Side) 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 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.
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.

on 28 September, 2015This is a great valve and it's at a great price. The handle is stout and the torque while opening and closing is really nice. I prefer the modular design as it's easier to handle with gloves on. I'm really happy with this product.
Do You Know Your Right From Your Left?
Modular valves come in right-hand and left-hand designs, referring to the side of the valve handwheel, not to which direction the valve opens. This can be confusing because there is not industry-wide agreement on the perspective from which the valve is viewed.
- Dive Rite assigns left and right from the perspective with your face toward the valve opening. If the valve is on and blowing air in your face, then you reach out with your left hand and can touch the valve handwheel knob it is a left handed valve. Thus Dive Rite says that the typical standalone valve is left-handed.
- Thermo assigns left and right from the perspective with your face away from the valve opening (i.e., the tank is on your back). If the valve is on and blowing air on the back of your neck, then you reach back with your right hand and can touch the valve handwheel knob it is a right handed valve. Thus Thermo says that the typical standalone valve is right-handed.
- DGX Premium Valves use the same method to assign left and right as Thermo does so a DGX Premium typical standalone valve is right-handed. However, because of the possibility of confusion we prefer to use the terms Typical and Uncommon to indicate the side of the handwheel.
While both right- and left-hand valves always close and open using the "righty-tighty, lefty-loosey" rule, this can cause problems when modular valves are mounted on single tanks. Well-meaning individuals who fail to notice a valve with the handwheel on the uncommon side and reach to check "air is on" might actually close a valve believing they are doing the diver a favor of opening it. To prevent this from happening, it's a good idea to call modular valve configurations to the attention of divemasters and buddies.
