Product Description

The San-o-Sub DIN/K Cylinder Valve is for use with both DIN and Yoke (K) regulator first stage fittings. The outlet on the cylinder valve is a five-thread 200-Bar DIN, designed to accept an included DIN to Yoke adapter insert. Available with either a Green or Black hand-wheel knob.

The convertible, cross-flow valves are made by San-o-Sub, a leading Italian manufacturer of medical, industrial and scuba valves. They are strong and reliable and are made from really top quality materials. The inner air passages were carefully studied in the design so as to guarantee top performance even, and above all, with the top performance regulators. The valve design ensures an excellent grip, facilitating opening and closing of the tank.

The valve has the shorter 200 bar, female DIN connection with 5 threads to connect your first stage DIN scuba regulator. The valve regulator connection comes complete with a threaded DIN to Yoke insert, which means it can equally be used for both INT bracket (Yoke) or DIN regulator connections. Use an 8 mmm Allen key to take the insert out or put it in.

The valve has a standard 3/4"x14 NPSM (NGS) parallel thread to fit the cylinder neck thread of most Australian Standard aluminium and steel tanks/cylinders/bottles. It has a 60° thread form, a pitch diameter of 0.9820 to 0.9873 in (24.94 to 25.08 mm), and a pitch of 14 threads per inch (5.5 threads per cm).

WARNING: Please ensure that you are fitting the valve to a cylinder with a matching thread. Getting it wrong is extremely dangerous.

Valve Oxygen Cleaning:
This valve is Nitrox ready up to 40%. If you are planning to use this valve on a cylinder with Enriched Air Nitrox (Nitrox) mixes from more than 40% up to 100% oxygen, or where partial pressure blending is used to create a Nitrox mix up to 40%, then it's essential for the safety of the cylinder user and the person filling the cylinder that the valve be oxygen cleaned and prepared with special o-rings, seats, and grease designed for exposure to pure oxygen. The cylinder should then be banded with the familiar yellow and green Nitrox band/wrap/sticker, and an Oxygen Clean 'In Test' inspection sticker applied. The Scuba Doctor can do all of this for you as an add-on service.

Tech Tip

Regulator Fittings and Scuba Valves

The Deutsches Institut Für Normung (DIN) is a German standards setting organisation. DIN 477 is a specification that recommends cylinder valve outlet and connector designs for specific types of gases and pressures based upon safety considerations. These various designs have deliberate incompatibilities to preclude the possibility of errors when handling different types of compressed gases at differing working pressures. The two valve outlets and connectors of interest for divers are the DIN 477 No. 13 and the DIN 477 No. 56 (formerly No. 50), both designated for use with compressed air.

The DIN 477 scuba valve outlet and regulator fittings are now the standard in Europe and are widely used by technical divers worldwide.Their thread form is also sometimes referred to as G 5/8" BSP. The regulator first stage DIN connector is a male screw type, and instead of clamping on to the outside of the valve as does the yoke, it screws directly into the female DIN outlet of the valve. The sealing O-ring is held in the end of the regulator connector rather than in the face of the outlet. The DIN 477 system, with its captured O-ring design, has proven to be very reliable for use with scuba gear.

Outlet/Connector #13 is from DIN 477 part 1, for cylinders with test pressure ratings up to 300 bar, and is commonly referred to in the dive industry by the slang term "200 bar", because most European and Australian dive cylinders with 300 bar test pressures have working pressures in the 200 bar range. The shorter 200 bar DIN connections have 5 threads.

Outlet/Connector #56 is from DIN 477 part 5, for cylinders with test pressure ratings up to 450 bar, and is commonly referred to in the dive industry by the slang term "300 bar", because most European and Australian dive cylinders with 450 bar test pressures have working pressures in the 300 bar range. The longer 300 bar DIN connections have 7 threads.

The two designs are nearly identical, but the 300 bar, #56 valve outlet is deliberately deeper with 7 threads so the shorter 200 bar, #13 connector with 5 threads will not be long enough to seat properly. This is a safety feature to prevent connecting a low pressure device to a high pressure supply. It's important to understand that the "200 bar" or "300 bar" descriptions are just slang terms that have nothing to do with the pressure ratings of the outlets and connectors themselves!
