XS Scuba's Valves are designed and manufactured for long life and heavy use. The Thermo by XS Scuba PVD one-piece reserve J manifold is no exception. XS Scuba's physical vapor deposition (PVD) finish manifold has a long lasting finish. PVD is not only a beautiful finish, but is also extremely durable. Before assembly the finished marine grade brass with triple bright chrome plating parts receive the PVD finish process. The parts are placed in a vacuum chamber, where a high power electric arc is discharged at the source material blasting away some into a highly ionized vapor which is deposited on the parts. XS Scuba's black colored PVD finish is accomplished with the use of Titanium Nitride. It provides the following advantages: Significantly harder exterior finish of 250 HV, a coating thickness of 0.2 to 0.3 micrometers, incredible resistance to salt water corrosion, increased scratch resistance and a very cool tech look".
Precision machined from high tension brass and chrome plated valve stems for years of service and corrosion free operation. The high pressure seat is nylon. The Manifold will accommodate both Yoke and DIN regulators with its removable 230 bar (3,336 psi) DIN insert which can be removed using a 1/4in hex key wrench. Easy grip soft rubber hand wheel with stainless steel insert ensures long life and large ribs make turning handle easy even when wearing gloves. Valve bonnets are copper crush washer sealed. Valve is equipped with a one-piece safety plug, has a 5/32in hex wrench dip tubes for positive retention and 3/4in x 14 NPSM inlet threads which fit nearly all DOT aluminum and modern steel cylinders. All this and more makes this the manifold of choice for the serious diver. The valve has a 3000 or 3300 (200 bars or 230 bars) service pressure. The Reserve J mechanism when in the up position activates at 600± 100 psi (50 ± 7 bars) and the diver will feel a difficulty in breathing from the regulator. To engage the reserve air the diver needs to pull down on the reserve mechanism to restore normal air flow. Valve is Nitrox compatible up to 40% and is covered by a 24 month limited warranty.
