Zero leakage American Standard bellows globe valve

Category：Pneumatic bellows shut - off valve

Specifically designed for various high-risk media. In addition to the packing seal, the valve stem incorporates a bellows, creating a dual-seal structure that effectively prevents leakage of hazardous media. Structurally, incorporating practical applications from domestic and international valve usage, the valve disc and seat sealing pair utilize highly corrosion-resistant PTFE and Stellite hard alloy. This configuration ensures stable sealing performance, safe and reliable operation, strong corrosion resistance, zero internal or external leakage, and effortless operation. Its key technical indicators—including sealing integrity, maintainability, and safety—meet the standards of world-renowned products, making it a viable replacement for imported alternatives.

Committed to providing high-end valve solutions for high-risk and harsh working conditions. The company has accumulated a profound technical foundation in the fields of petrochemicals and chemical equipment, especially in the core advantages of special valves such as anti-corrosion and leak prevention.

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.
