Why Cryogenic Liquid Relief Valves Are Essential For Working With Industrial Gases

Posted on

The use of industrial gases in various manufacturing applications is a common practice. Some of these gases (such as hydrogen, nitrogen, oxygen, argon, and carbon dioxide) become liquid after they reach the lowest possible temperature. Cryogenic liquids are vital in the normal operations of numerous industries, such as freezing organic tissues in the medical field, assisting with food preservation in the agricultural sector, and cooling down parts during the automotive manufacturing process. Handling these extremely cold liquids is difficult to do without the right valves to keep the material under control. Here are 3 ways that cryogenic liquid relief valves are necessary for working with industrial gases. 

1) Cryogenic liquid relief valves ensure the proper storage of industrial gases.

Cryogenic liquids must be stored in special receptacles that can withstand frigid temperatures for extended periods of time. To reduce any safety hazards, these containers should be equipped with cryogenic liquid relief valves that can be opened and closed as needed to sustain the correct pressure measurements. For instance, the longer a cryogenic liquid is in storage, the more likely it is that extensive pressurization can occur. When the pressure has built up to precarious levels, a relief valve will open to release gas until the pressure is back to normal. If cryogenic liquid relief valves are not installed on the storage container, then pressure fluctuations can cause a fire or explosion. 

2) Relief valves are needed to safely transport cryogenic liquids.

Moving cryogenic liquids from one place to another can also be a challenging job. As the locations change during transportation, the temperatures in new and different environments will affect the condition of the cryogenic liquids, regardless of the container. Traditional valves are not well-suited for this situation because they are susceptible to breaking down as the temperatures shift. Cryogenic relief valves, on the other hand, help to maintain a steady temperature range while the liquids are in transit. Gas leaks can happen quickly and without warning, once a relief valve stops working, so carrying cryogenic liquids requires the use of valves that are specifically meant for sub-zero materials.

3) Cryogenic liquid relief valves can prevent your machinery from malfunctioning.

Industrial equipment that utilizes cryogenic liquids can become severely damaged if the appropriate amount of pressure is disturbed. Hoses, lines, and gaskets could all malfunction as a result of a sudden pressure surge, leading to dangerous consequences. For this reason, cryogenic liquid relief valves are put in place to alleviate major increases in pressure. The valves provide protection from hazards that could injure the technicians who operate the machinery. Furthermore, cryogenic liquid relief valves help to keep equipment running accurately over a long lifespan. The valves allow the machinery to perform without fail and control the pressure so that all the moving parts can continue to work as intended.

Proper storage, safe transportation, and long-term machinery performance are all reasons to install relief valves when you need to work with industrial gases and cryogenic liquids in any capacity. Contact a cryogenic liquid relief valve supplier for further details.
