Home >> Diving regulator first stage >> R102 DIN YOKE ICE

The regulator first stage is an integral part of any scuba diving gear. This device basically has the function of minimizing a scuba tank’s air pressure (usually around 3,000 psi) to a medium pressure of 125 to 150 psi above the ambient pressure. This what some may call intermediate air pressure is then fed into the regulator second stage to be converted into the ideal gas that scuba divers consume.

The first stage regulator comprises of two air chambers, which are separated by either one or a series of valves whose job is to permit the gas from the scuba tank to flow in a more controlled manner. When the regulator first stage is not pressurized, these valves are normally open. However, once fitted to the cylinder air flowing from the tank passes into the first chamber and they close when it reaches the second chamber and is converted into a medium pressure.

This device is attached to the cylinder by a knob or screw mechanism that is commonly known as the yoke fitting. Alternatively, some of these products make use of a din fitting that is essentially a direct screwing mechanism. This kind of fitting offers the added advantage of been able to resist great air pressure from the cylinder, which permits the utilization of high pressure steel scuba tanks. Both yoke and din fittings can come with either a diaphragm or piston construction. Whose primary function is the start or stop air flowing through the regulator first stage as the diver inhales or exhales respectively.

These products can also be classified as balanced or unbalanced. The first category has the capability of delivering air pressure from the tank at a constant rate throughout the entire dive. This in simple words means that such a delivery cannot in any way be affected by the distinct level of air pressure in the tank. Which as most seasoned scuba divers would readily know, decreases with continued consumption. The unbalanced variety on their part, are significantly affected by a decrease in air pressure in the scuba cylinder as well as a change in depth. This results in a great difference in the diver’s breathing ability, when submerged.

A regulator first stage also comes with sealed low pressure outlets that can be connected with a submersible pressure gauge (SPG) or even a gas integrated diving computer. Both of which permits the scuba diver to conveniently take accurate cylinder air pressure readings on demand.

Going back to the yoke fittings, these products happen to be the most prevalent of their kind, and are used to clamp together the air open hole that is located on the regulator with that of the scuba tank. Yoke fittings are usually loosely screwed, and once the tanks valves are opened, the gas pressure emerging from it completes the seal, together with an O-ring.

The regulator first stage also feature a high pressure port that is designed to allow a high pressure hose to be seamlessly connected with an appropriate pressure gauge. Like earlier mentioned, this device also comes with several ports that are meant to fit with low pressure hoses. Whose main job is to transmit gas to other critical components that can serve as some kinds of second stage valves.

When it comes to the advantages of the regulator first stage nothing could be more apparent. This scuba diving device has the critical function of converting the high pressure found in scuba tanks into an intermediate level, before it is fed into the regulator second stage. Which then converts it to ambient pressure that is safe for scuba divers’ consumption. A thing that would be impossible if they accessed such gas at the high pressure that it is stored in the cylinders.

The balanced varieties of this device also go a long way in making sure that the diver is always supplied with a constant rate of air pressure throughout the dive. The regulator first stage on the other hand, has the task of compensating air pressure as it decreases in the scuba tank when the diver decides to change their depth. All in all, this product has been known to significantly enhance the ultimate scuba diving experience in more ways than you could ever think possible.
