The objective; design the most reliable HP valve in the world. Every engineer knows the benefi ts of using balls in valve arrangements, since they will never be misplaced and will always fi nd their perfect position.Unfortunately, varying upstream pressures will either push the ball too fiercely into the seat or leave it unsecurely loose, giving unbalanced characteristics. By inventing the floating seat (which automatically repositions the ball) the increased upstream pressure is balanced equally with increased and counter-acting compression forces from the pressure adjustment spring, so maintaining the benefits of having a perfect ball as the sealing element. The Xstream regulator is also self-balancing, which gives the same high performance irrespective of the pressure in the cylinder. When the seat is moved upwards by the high pressure, the design causes the upper pressure spring to compress and thus exactly self-balance the powers of pressure. Xstream also has a built in anti freeze protection in its construction.
TDA (Thermo Dynamic Antifreeze) ensures that the through-flowing water keeps the ice away, entirely without fluids or extra diaphragms. The Xstream Deep: The Xstream Deep: rated for use down to 200m and for use with mixtures containing helium (He). 3 Low Pressure Ports + 1 High Pressure Port. Trimix, nitrox, oxygen and air. 200 m / 656 ft approval Norwegian Norsok U101 standard.
Approved to cold water standard, EN250. Approved for use under ice down to -1,6 °C / 29.12 °F without CWD kit. Unique internal Thermo Dynamic Anti-freeze system (TDA).
2nd stage could be used either from left or right. Normal DIN 300 bar 5/8 Thread. DECO / OXYGEN 1:ST STAGE (OXYGEN, EAN, AIR) O4 stands for oxygen engineered, oxygen compatible, oxygen clean and oxygen approved.It is not just a viton configured air regulator, but in detail engineered for pure oxygen. The Xstream Deco is made as a bottom mounted version. The connection stem is sealed with a pure copper washer sintered onto the filter.
It has been tested for 360 bar (5221 psi) adiabatic compression oxygen shocks of less than 20 ms (heated to 60°C/140°F) according to EN 738-1. To make the test even more severe than required, it is tested with 99.95% purity of oxygen. Directly from the box, it is cleaned to NASA Specification  Cleaning test Level 100 (particle contamination) and NVR levels less than ASTM G63 Level C, <50 mg/m2 (hydrocarbons). The Xstream Oxy90 1st stage is only used on the Mk VI Discovery Rebreather.
