What is Cryogenic Ball Valves?
Cryogenic Ball Valves extended stem and bonnet to position the stem packing above the cryogenic fluid and providing a column of warmer vapor that insulates the stem seal from the affects of low temperatures.
How does a cryogenic valve work?
Cryogenic valves are maintained naturally closed to protect and properly retain cryogenic gases or other mediums. A cryogenic valve responds to high pressure by pushing into the open position, allowing the gas or other media to pass through easily. The open flow will last until the pressure decreases once more, at which time it swings back and seals with a unique metal seat bubble-tight shutdown to stop any leaking.
The external pressure has some influence on how well a cryogenic valve functions. A cryogenic valve is typically maintained in a closed state. As a result, the media inside the valve will be kept inside and won’t leak into the atmosphere. These valves are precisely made to respond to pressure increases. The valve is pushed into the open position by increasing pressure, which causes the medium to flow. Until the pressure drops, this flow will continue.
Materials Used In Making Cryogenic Valves:
Aluminum, stainless steel, brass, Incoloy, bronze, zirconium, etc., are typical building materials for cryogenic valves. Typically, the seal material is made of graphite or PTFE material.
The valve’s material selection depends on the temperature range that it can sustain. The design of the valve will result in cracks, internal and external leakages, and other severe problems if it is not made from a suitable material.
What is the ball valve for cryogenic application?
Ball valves designed for use with cryogenic fluids have longer stems and bonnets. With this layout, the cryogenic fluid channel is above the stem packing. The extended stem creates a column of insulation. The cold liquid becomes a warm vapor by applying pressure to the column.
Cryogenic Valve Applications:
Industrial facilities are the main locations of cryogenic valves, which take advantage of procedures that can be carried out at extremely low temperatures. As a result, several of these cryogenic valve applications are highlighted in the following sections.
Oil And Gas Industry
Cryogenic valves manage liquefied gases like methane, liquid nitrogen, and helium in the oil and gas industry. These substances cool to cryogenic temperatures and are kept in a liquid condition thanks to their simplicity and safe non-pressurized storage and transportation. More significant amounts can thus be moved or kept in storage for an extended period while the piping system runs at significantly lower pressure levels and ensures power generation. To avoid corrosion issues farther down the line, condensate, moisture, and CO2 must be removed before these gases are cooled into a liquid.
Chemical And Petrochemical Industry
In the chemical processing industry, several products, including liquid oxygen, ethylene, and liquid nitrogen, require handling at very low temperatures. Cryogenic valves are the ideal option for this use. They are also excellent for transporting liquids, such as LPG.
Air Separation
Several pressure techniques are used to separate the various gases in the air. These plants make excellent use of cryogenic valves.
Food And Beverage Industry
Cryogenic valves are widely used in factories that produce processed food and drinks. Using cryogenic pipes and valves, these things are moved into and out of freezers.
Health Industry
Cryogenic valve applications are constantly growing and are even used in the medical sector—both storage areas where medical equipment is kept and pipelines that transfer gases like oxygen contain them.
Standards Of Cryogenic Valve:
Although some businesses have unique specifications for cryogenic valve service, the majority of these specifications are based on engineering norms like ASME 16.34, BS 6364, and ISO 21011.
ASME 16.34:
Critical criteria about valve-related components, including threading, flange, and welding end, are included in ASME 16.34.
A few of the specifics are:
Require valve closure tests, leakage detecting devices, and valve shell tests.
Description of pipe marking criteria and nominal pipe size.
Flange removal criteria, electrical continuity, and material selection specifications.
BS 6364:
This British Standard lays out the design, production, and testing specifications for valves used in cryogenic service.
The following is a list of its requirements:
The cryogenic valve design must include enlarged bonnets and glands. The extension’s length must also be sufficient to keep the stem packing at an appropriate temperature. Consequently allowing it to operate within the packaging material’s usual temperature range.
Flat-seated discs are not permitted for globe valves, according to BS 6364. They should be tapered or conical instead.
Procedures for the production and prototype testing of valves are also included in BS 6364.
The cryogenic valve design for combustible service must provide electrical continuity to avoid the accumulation of static electricity.
Valves used in liquid service must be able to operate with their stem at a height of at least 45 degrees above horizontal. Similarly to this, gas service valves must be capable of opening and closing with their stems.
ISO 21011:
This international standard lays out the design, production, and testing specifications for valves used in the operation of cryogenic fluids. The standards include addressing operation at cryogenic and ambient temperatures.
The following is a list of its main recommendations:
According to this standard, valve parts made of metallic and non-metallic materials should adhere to ISO 21028-1 and ISO 21028-2 standards.
Cryogenic valves must operate safely between their rated lowest temperature and 65°C to carry out their intended duty. In addition, they have a specific pressure range they must work inside.
Cavities that could cause a buildup of pressure and the entrapment of liquid are prohibited by ISO 21011.
