Bellows globe valves, fluorine lined valves, and special material valves are widely used in many industrial fields, especially in environments with strong corrosion and high-risk media, where their application is indispensable. These valves have unique advantages and can meet various harsh working conditions.
1、 Application and advantages of bellows globe valve
Bellows globe valves are mainly used in industrial fields such as petroleum, chemical, metallurgical, and power. Its advantages lie in:
1. The corrugated pipe design enables the valve to have excellent sealing performance, preventing medium leakage.
2. The on-off operation of the globe valve is convenient and the flow control is precise.
3. The corrugated pipe material is excellent, resistant to high pressure and corrosion, and has strong adaptability.
2、 Application and advantages of fluorine lined valves
Fluorine lined valves are widely used in industrial fields such as chemical, pharmaceutical, and environmental protection, especially for controlling highly corrosive media. Its advantages include:
1. Fluoroplastic lining has good corrosion resistance and can adapt to various highly corrosive media.
2. The valve operates stably, has a small opening and closing torque, and has a long service life.
3. Fluorine lined valves have good anti scarring and anti blocking performance.
3、 Application and advantages of special material valves
Special material valves are widely used in petroleum, chemical, pharmaceutical, food and other fields, especially suitable for high-risk media and extreme working conditions. Its advantages include:
1. Using special materials such as super stainless steel, titanium alloy, etc., it has extremely high corrosion resistance.
2. The valve has a compact structure and strong flow capacity, which can effectively reduce fluid resistance.
3. Special material valves have good fatigue resistance and can adapt to frequent operations and changing working conditions.
For high-risk media, special material valves can provide good safety performance and reduce the risk of leakage.
In summary, bellows globe valves, fluorine lined valves, and special material valves have a wide range of applications in industries such as petroleum, chemical, and pharmaceutical. They each have unique advantages and can work stably in environments with strong corrosion and high-risk media, ensuring production safety. With the continuous development of industrial technology, the application scope of these valves will further expand, making greater contributions to the development of various industrial fields.
