Product Description

Cryogenic Control Globe Valve

Features

Cryogenic control valve is a valve specially used for fluid control in low temperature environments. It is widely used in industrial fields that require the regulation and control of media under extremely low temperature conditions.

Cryogenic control valves are typically used to handle systems involving liquid or gaseous media that have special properties and requirements at low temperatures. For example, they are commonly used in liquefied storage and transportation systems, refrigeration and air conditioning systems, liquid oxygen and liquid nitrogen systems, cryogenic chemical processes, etc. in the liquefied natural gas (LNG) process.

Cryogenic control valves are designed and manufactured with the challenges and requirements of cryogenic environments in mind. They feature special materials and sealing mechanisms to ensure reliability and durability in extreme cold temperatures. Additionally, they often have an insulated design to reduce heat transfer and prevent freezing or condensation.

The function of the cryogenic control valve is to control the flow, pressure or temperature of the medium by adjusting the opening of the valve. They can achieve two-position switch control or continuous adjustment control to meet the needs of different application scenarios.
 

 

Our Advantages

When selecting special valves for cryogenic applications, it is important to consider the following types and selection tips:

Valve Types: There are several types of valves commonly used in cryogenic applications, including globe valves, ball valves, gate valves, and check valves. Each type has its own advantages and limitations, so the selection should be based on the specific requirements of the application.

Material Selection: Choosing the right materials is crucial for cryogenic valves to ensure their performance and reliability in low-temperature environments. Materials such as stainless steel, brass, bronze, and certain alloys are commonly used due to their excellent mechanical properties and resistance to low temperatures.

Sealing Mechanism: Cryogenic valves require effective sealing mechanisms to prevent leakage and maintain system integrity at extremely low temperatures. Different sealing mechanisms, such as metal-to-metal, soft-seated, or elastomeric seals, may be suitable depending on the application requirements and temperature range.

Insulation and Heat Tracing: In cryogenic applications, valves may need to be insulated or equipped with heat tracing systems to prevent freezing or ice buildup. Proper insulation and heat tracing measures should be considered to ensure the valves' functionality and prevent operational issues.

Compliance with Standards: It is essential to ensure that the selected cryogenic valves comply with relevant industry standards and specifications for cryogenic applications. This ensures the valves' performance, reliability, and safety in low-temperature environments.
