Product Description Of Cryogenic Globe Valve

Cryogenic valves are very similar to conventional valves, with the exception of materials and features such as an extended stem. These extended stems allow handles or actuators to be at an ambient temperature.

Cryogenic valves normally refer to valves with working temperature below -110°C, widely used in industrial gas, LNG, LPG and other low temperature applications and regulating or controlling the flow of cryogenic gases, slurries or liquids at low temperatures. These valves come in different shapes and sizes so that they can handle different pressures required by various applications. Some of the common types of cryogenic valves are butterfly valves, relief valves, ball valves and globe valves. The user can manually operate or automate cryogenic valves to handle large systems.

Factors Considered In The Selection Of Valve Sealing Surface Materials

The sealing surface is the most critical working surface of the valve. The quality of the sealing surface directly affects the service life of the valve. The material of the sealing surface is an important factor to ensure the quality of the sealing surface. Therefore, the following factors should be considered when selecting valve sealing surface materials:

①Corrosion resistance.
"Corrosion" is the process in which the sealing surface is damaged under the action of the medium. If the surface is damaged in this way, the sealing performance cannot be guaranteed. Therefore, the sealing surface material must be corrosion resistant. The corrosion resistance of the material mainly depends on the material and its chemical stability.

"Abrasion" refers to the damage caused by friction of the material during the relative movement of the sealing surface. This kind of damage will inevitably cause damage to the sealing surface. Therefore, the sealing surface material must have good scratch resistance, especially for gate valves. The scratch resistance of a material is often determined by the internal properties of the material.

③Erosion resistant.
"Erosion" refers to the process of destroying the sealing surface when the medium flows through the sealing surface at high speed. This kind of damage is more obvious in throttling valves and safety valves used in high-temperature and high-pressure steam media, and has a great impact on the damage of sealing. Therefore, erosion resistance is also one of the important requirements for sealing surface materials.

④ There should be a certain degree of hardness, and the hardness will drop greatly under the specified working temperature.

⑤The coefficient of linear expansion of the sealing surface and the body material should be similar, which is more important for the structure of the inlaid sealing ring, so as to avoid excessive stress and loosening at high temperatures.

⑥Used under high temperature conditions, there must be sufficient anti-oxidation, thermal fatigue resistance and thermal cycle problems.

Under the current situation, it is difficult to find a sealing surface material that fully meets the above requirements. It can only meet certain requirements according to different valve types and uses. For example, valves used in high-speed media should pay special attention to the erosion resistance requirements of the sealing surface; when the medium contains solid impurities, the sealing surface material with higher hardness should be selected.
