Low Temperature Cryogenic Gasses

Valves built from materials that will withstand extreme temperature changes usually below -238°F (-150°C) while maintain their mechanical properties.

Cryogenic solenoid valves are designed to control the flow of cryogenic fluids, which are substances that have extremely low temperatures, usually below -238°F (-150°C). These fluids, such as LN2 (liquid nitrogen), LOC2 (liquid oxygen), and He (liquid helium) are used in various applications like cryogenic storage, cooling systems, and rocket propulsion.

What makes our cryogenic solenoid valves unique?

Material selection

Our cryogenic solenoid valves are made from materials that can withstand extreme temperature changes and maintain their mechanical properties at cryogenic temperatures. Typically stainless steel, brass, and bronze are used for valve components due to their low thermal conductivity, excellent corrosion resistance, and compatibility with cryogenic fluids.

Seals and gaskets
Seals and gaskets in cryogenic solenoid valves need to be made from materials that remain flexible and maintain their sealing properties at very low temperatures. We use elastomers like PTFE (Teflon), PCTFE (Kel-F), and FKM (Viton) as they have low-temperature flexibility and high chemical resistance.

Thermal Expansion and Contraction
Valves withstand extreme temperaturesCryogenic solenoid valves experience thermal expansion and contraction of their components due to extreme temperature changes. This can cause valve components to change shape, leading to potential leaks or malfunction. Our designs such as larger tolerances and clearances are incorporated to accommodate these changes.

Insulation and Heat Transfer
If heat transfer is an issue, these valves can include insulation like vacuum jackets or multiple layers of insulation materials. This helps to prevent the valve components from freezing and keeps the external surfaces at a safe temperature for handling.

Extended Bonnet Design
In some designs, cryogenic solenoid valves may have an extended bonnet design that keeps the solenoid coil and other electrical components away from the cold fluid. This helps to protect the electrical components from extreme cold and prevent the formation of frost or ice on the coil, which could affect the valve's operation

Who uses cryogenic solenoid valves?

Applications of cryogenic solenoid valves are often mission critical. The ability of cryogenic solenoid valves to control the flow of fluids under extreme temperature conditions makes them invaluable in industries and applications where precision, reliability, and safety are of utmost importance.

Gas Liquefaction Plants
In gas liquefaction plants, cryogenic solenoid valves control the flow of gas while converting natural gas or other gases into their liquid state. This reduces the volume of the gas for storage or transportation purposes.

Cryogenic Storage and Transportation
Laboratories, medical facilities, and industrial settings use cryogenic storage and transportation for preserving biological samples, storing liquefied gases, and cooling superconducting magnets.

In medical and biological research, cryogenic solenoid valves are used to preservation of biological samples like cells, tissues, and organs at very low temperatures for long-term storage and potential future use.

Food and Beverage 
Quick freezing and cooling applications use cryogenic solenoid valves to help control the flow of cryogenic fluids like liquid nitrogen or carbon dioxide to rapidly freeze food products preserving their quality, taste, and texture.

Rocket Propulsion 
Cryogenic solenoid valves play a crucial role in the aerospace industry, particularly in the control and management of  liquid hydrogen and liquid oxygen fuels used in rocket engines. These valves help to regulate the flow and pressure of cryogenic propellants to ensure proper combustion and thrust.

Semiconductor Manufacturing 

In the semiconductor industry, cryogenic solenoid valves are used to control the flow of ultra-pure cryogenic fluids for cooling sensitive electronic components during manufacturing to maintain the quality and performance of the electronic devices.

Superconducting Systems 
Particle accelerators, magnetic resonance imaging (MRI) machines and quantum computing devices require cooling fluids like liquid helium at ultra-low temperatures to maintain superconductivity.
