Meet the demands of all your cryogenic applications with the right valve

If you work in an industry that utilises cryogenic valves, then it is good to know more about the valves, the various types, and when to use each one. Habonim offers these valves, and can supply you with any cryogenic product you need.

First of all, these types of valves are made to be used in cold applications. They are used a lot in companies that use liquefied natural gas (LNG) or compressed natural gas (CNG). For example, you would see it in the oil and gas industry. In addition, they use a simple pressure increase to compress their volume. They are used to help transport and store all cryogenic gases safely. Moreover, they are kept in a closed position to keep cryogenic gases, and they are meant to react to high pressure, which pushes the valve into the open position to allow the gas to flow through. The open flow will continue until the pressure goes down, and then it will bend back and seal with a metal seal in order to prevent leaking.

Furthermore, if you’re wondering what valve you should use; these are the main styles and their uses:

Globe valves: These valves are spherical in shape, and they have an internal movable disc which is called the obturator. It rotates at 90 degrees to the plane of its body seat. You can rely on this valve to have long-term sealing performance. However, they aren’t the best choice for situations that require flow rate.

Ball valves: These valves use a ball as an obturator, and it includes a polytetrafluoroethylene body seat. These valves are good for jobs that require good flow, but are prone to wear and tear along the seals and the ball.

Top entry ball valves: These valves are similar to standard ball cryogenic valves, but this one is a newer model, and it has a one piece design with butt welded connections that makes it easy to maintain. Furthermore, it lacks mechanical joints, which makes it a good choice for fire safe applications.

Gate valves: These valves use a wedge-type gate as the obturator which swings to close parallel to the body seat. They are also a good option for flow characteristics but are prone to wear and tear.

Butterfly valves: This type of valve uses a circular disk at the centre, which allows butterfly cryogenic valves to have a short length, which makes them lighter and cheaper. They are also user-friendly, but it is important to not over use them.

Additionally, you might be wondering why you can’t use another type of valve. The answer is that they don’t have the power to perform efficiently. It is too much of a risk to have cryogenic gases leak, and standard valves are too sensitive to extreme temperatures. This can cause breaks in the seal. That is why there are companies like Habonim who can help you choose the right valve for your needs. Contact them today for information on products and any demanding project.
