Valves Used in Numerous Industries

The Many Places You’ll Find Valves

Anywhere that a fluid or gas flows through a pipe, you’ll find valves. They regulate flow, stop it, and start it again. Safety and relief valves protect property and lives from over pressurization.

CPV Manufacturing’s high-quality valves are used in some of the toughest industries and harshest environments on Earth. Here are a few of the places you might find them:

Marine & Shipbuilding

Ships are complex. From fuel distribution and storage to cargo loading and unloading, the ballast and bilge systems, refrigeration, and hydraulic systems, there’s no shortage of valves on a ship. You’ll find all types, from metal-seated ball and butterfly valves to relief, check, gate, and globe valves.

Large ships havecomplex systems of pipes and valves to direct the fuel. US Navy aircraft carriers use CPV valves in the lifting of aircraft to the flight deck and in bringing the jets to an abrupt halt when they land.

Marine settings are some of the most hostile…even fresh water is damaging to pipe and valve systems. Plain water causes oxidation to susceptible materials. In seawater, oxidation is compounded not only by the effects of salt, but the sand and mud, plant particles, microorganisms, and small animals. Certain bacteria can produce hydrogen sulfide, ahighly corrosive toxic gas. Valves used in naval settings have to be able to stand up to the inhospitable aquatic environment.

Oil and Gas

Oil and gas production requires heavy-duty valves and pipes. From offshore oilrigs to onshore processing and distribution, a multitude of valves will be found along the way.

Offshore rigs and facilities

Offshore oil rigs have several different functions, each requiring pipe and valve systems of their own. Piping the oil or gas from the land beneath the water requires valves and equipment that can work under as much as 10,000 feet of water.

The Christmas tree valve assemblies that can be seen on top of wellheads are a combination of valves including gate valves and chokes. Their primary function is to control the flow out of the well. Christmas trees are made to handle up to 10,000 psi of pressure and can be found both on land and in offshore wells.

Once the oil has been extracted, typically the water will be removed from the hydrocarbons, and natural gas liquids will be separated from the fluid stream. Sometimes sour gas, raw petroleum containing hydrogen sulfide, is present. Due to its highly corrosive, flammable, and toxic nature, special handling is required including the use of corrosion-resistant valve materials.

The valve that you’ll see the most on an oil rig is the ball valve, although other types of valves are also used.

The American Petroleum Institute (API) as well as the American Society of Mechanical Engineers and NACE (formerly the National Association of Corrosion Engineers) have standards and recommended practices that are to be followed depending on the circumstances. Specifications that may apply on an oil rig are: NACE MR0175, API 594, API 600, API 602, API 608, and API 609, API 6D, API 6A.


The underground pipelines that transport petroleum have valves spaced at intervals, specified by codes and laws, for their entire length. If there were to be a leak, these emergency shutoff valves would be closed, minimizing potential hazards, loss, and environmental damage. Shutoff valves also allow for maintenance to be performed.

Underground pipelines also have stations where they come above ground to allow for cleaning or inspection. The valves at these stations must be able to be fully opened so that the cleaning and inspection equipment can be fit through. Gate or ball valves are typically used at these stations.

Pumping stations containing gate, ball, and check valves are located along the length of the pipeline in order to keep the fluid moving.

The American Petroleum Institute specifications API 6D apply specifically to pipeline valves.

Refinery and petrochemical

If you’d like to see an example of almost every type of valve, a large refinery is the place to be. High temperatures and corrosive fluids are common in refineries. Such valves require extra resistance, which can be accomplished with the use of thicker walls and the right materials using metals ranging from carbon steel to high-nickel alloys.

Specifications API 594, API 600, and API 608 may apply to the valves used in a refinery.

Liquefied Natural Gas

Liquefied natural gas is about 600 times smaller in volume than in its gaseous state. Achieving this liquid state requires that it reach a temperature of -265 degrees F. The pipes and valves used in this process are large, so they must handle high pressure as well as the very low temperatures needed for liquefaction. Popular valve types in LNG production are quarter-turn ball and butterfly valves.

No valve packing materials, however, can withstand such low cryogenic temperatures. To work around this factor, a gas column is used. This column keeps the packing away from the cryogenic conditions so that it doesn’t freeze which would immobilize it.

Gas Separation

Like LNG, gas separation also occurs at very low temperatures. The valves used for gas separation must be tolerant of very low temperatures.

As in LNG production, a gas column is used to separate the packing from the low-temperatures needed for gas separation.


The 316/316L grade of austenitic stainless steel is the metal of choice where corrosion is of moderate consideration. Production of highly corrosive chemicals requires the use of even more heavy-duty metals and alloys.

Chemical production is usually done at lower pressures than in the industries discussed above, so pressure is less of a factor than it is with others.

Linear valves are still used for some chemical processes, but the resilient-seated ball valve is popular for many chemical applications due to its zero-leakage shutoff and compact size. Diaphragm, pinch valves, gate and globe valves are used as well.

This is just a sampling of all the places valves are used. Even if you’re not directly involved in one of the industries we serve, there’s a pretty good chance that your daily life has been touched in some way by a CPV valve.

The Characteristics of Quality Cryogenic Valves

When selecting a valve, it’s important to understand where cryogenic temperatures start. In the oil and gas industry, the cryogenic temperature range starts at –238 degrees Fahrenheit. Certain gases are considered cryogenic because they take more than just an increase in pressure to compress their volume.

Understanding Valves

cryogenic valves finalNathaniel Paxton, Cameron product manager, said, “A general rule is that continuous temperatures less than –100 degrees are considered cryogenic service and warrant specific valve preparation.”

Severe temperature variations of a cryogenic nature can be dangerous for the valve. When heat is gained from the environment, the components of a valve (body, bonnet, stem, stem seals, ball, seats, etc) contract and expand. That’s why there’s insulation in valves and piping.

During gas processing, we deal with the physical properties of gases, such as liquefied natural gas, nitrogen, oxygen, argon, and helium. The liquids don’t want to be at atmospheric pressure and can violently transform.

There’s always the buildup of pressure in the processing of cryogens because of the heat gain from the environment. For this reason, the valve/piping system must be designed specifically to allow for the buildup of pressure.

Selecting a Valve

2 Mechanical EngineersMany choose quarter-turn ball valves for valve type in cryogenic service because of their tight shut-off capabilities. For larger valves, gate valves are utilized over ball valves.

For piping connections, flange and welded configurations are typically used, but it’s also about customer preference.

Ensuring Valves Are Clean

While cryogenic valves do not need to be cleaned and assembled in a clean room, valves that go into critical services, such as oxygen or other products that would be specified by the end user, do need to be cleaned.

Safety is the top priority at CPV Manufacturing, so making sure that our valves and fittings are clean is crucial. These were our thoughts when we made an investment and installed our 10,000 class oxygen clean room in our facility.

We provide commercial oxygen cleaning for the compressed gas market, and our valves are used in high-pressure oxygen systems. Our class 10,000 clean room is above and beyond the industry standard.

In addition to the compressed gas industry, we also provide oxygen cleaning for a wide array of industries such as government officials and the petrochemical industry.

Cryogenic distributionWithin the cryogenic distribution industry, safety is at the forefront of importance. This means, new innovations are constantly being considered to make the industry as safe as possible. In addition to safety, improving operational efficiencies is also a critical part of the industry. There’s a lot of pressure to reduce the cost operational efficiency because of this competitive market.

Innovations to increase safety in the industry are focused on reducing the likelihood of accidents, while innovations to improve operational efficiency are focused on vehicle stability and protecting operators.

Companies use these factors to help evaluate and select the best distribution equipment for their own business. Learn more about safety and operational innovations to stay on top of the trends in cryogenic distribution and select the most appropriate equipment for your business.

Reducing Risk of Roll-Over

One of the biggest risk factors that exists in the industry right is the risk of roll-over accidents. Most road accidents are related to roll-overs and poor trailer design. Trailers are not handling properly and are not very stable, resulting in roll-overs.

To reduce roll-overs, world-class manufacturers have been concentrating on lowering the center of gravity. When the center of gravity is lowered and combined with a wide wheelbase, the trailer is less likely to roll over.

Dividing the height of the center of gravity by the wheelbase width at the axle will allow you to calculate if your trailer is more or less likely to roll-over. If the number is high, it’s more prone to roll over.

Additional Safety Innovations

Incorporating additional safety innovations that utilize state of the art technology will increase your trailer’s safety. Learn more about these features.

Advanced Roll Stability Support (RSS): Advanced roll stability support has automatic braking action to reduce to risk of roll-over. This feature is integrated in the EBB system to measure speed, load and transverse acceleration. Brakes are automatically applied in the case of a potential roll-over.

Rear Door Warning System and Actuated Shut-Off Valve: This system warns the driver when the trailer is still connected to a tank, or results in automatic breaking of the vehicle.

Remote Closing System: This closes the main shut off valves so that the product is inside the trailer.

Overfill Prevention: This feature available on recent designs has pressure switches that automatically close main valves. This avoids over-filling.

Improving Efficiency

In the cryogenic distribution industries, companies are looking to optimize the cryogenic trailer. This entails designing it to carry the largest amount of liquid volume while also meeting the country’s road regulations that limit weights and dimensions. The manufacturer’s objectives are the increase the volume of the product by using the lightest material.

Cryogenic Equipment Trends in 2015

Cryogenic technologies are significant in the industrial gases business and have been since the beginning of industrial gas supply chains. They’re just as significant today as they were then, providing a new handle for the liquefied natural gas market (LNG). LNG has driven growth for cryogenic equipment across the board in recent years.

2015 was a year of cryogenic equipment trends with a great deal of growth and technology development throughout cryogenic valves, pumps, and storage vessels. Review the biggest trends in the cryogenic technologies within the past year.

Cryogenic Valves

Cryogenic EquipmentCryogenic valves are used in storage, processing, and distribution and demonstrate the growth of LNG. The growth of the LNG market is affecting the businesses that manufacture cryogenic valves in a variety of ways.

As a result of the LNG boom in recent years, companies are experiencing a vast increase in the sale of valves. Compact valves that suit LNG trucks, OEM, skid and refueling stations are also in demand.

Due to the rise in the development of new products for cryogenic bulk tanks and transportation vessels, companies have also reported that sales of bronze and stainless steel globe valves and angle relief valves have been increasing.

Cryogenic valves are crucial in LNG plants, and companies have seen an influx of orders in the industry from large LNG plants. However, because of falling oil prices, the LNG business tapered in 2015. LNG growth may be on hold, but the ship-fueling market remains strong and may prove that this halt in growth is temporary.

Cryogenic Tanks and Tankers

Due to the LNG boom, cryogenic tanks and tankers are in demand. This increasingly competitive industry is driven by tight margins to optimize efficiency, which is why payload optimization was still a pressing issue in 2015. It’s crucial to reduce the carbon footprint while increasing distribution productivity.

Because distribution costs weigh heavily in the overall cost of the product at 50% of all air gas industry costs, distribution solutions must reduce consumption and emissions over the life of the asset.

Cryogenic Pumps

LNG has also driven growth in the cryogenic pumps business over the past year and previous years. While companies contribute the new developments in the hydrocarbon industry as the leading factors in the market, it’s unknown how the dropping oil prices will affect the dynamic of the last year.

Just like cryogenic tanks and tankers, there’s a need for higher efficiency and performance, and this need has influenced cryogenic pump development. Engineers are working toward creating machines that are functional and compact.

Throughout 2015, the cryogenic technology industry continued to be an integral part of the industrial gases business.
