High-pressure ball valve is a valve whose opening and closing parts (ball) are driven by the valve stem and rotate around the axis of the valve stem. It is mainly used in hydraulic machinery equipment, hydraulic switches, natural gas, etc. This kind of valve came out in the 1950s. With the rapid development of science and technology, in just 40 years, high-pressure ball valves have rapidly developed into a major valve type.

There are many types of high-pressure ball valves, including metal-sealed high-pressure ball valves, soft-sealed high-pressure ball valves, high-pressure forged steel ball valves, high-pressure ball valves for oxygen-containing media and high-pressure electric ball valves.

1. Metal-sealed high-pressure ball valves adopt a metal-to-metal sealing structure and can withstand high pressure and temperature. This type of ball valve is mainly used for fluid control under high temperature and high pressure conditions, such as petroleum, chemical industry, natural gas and other fields. Its corrosion resistance and wear resistance enable it to perform well in harsh environments.

2. Soft-sealing high-pressure ball valves use elastic materials as seals, usually polytetrafluoroethylene (PTFE) or polyethylene. This type of ball valve has good sealing performance, can effectively prevent leakage, and is flexible in operation. It is suitable for some occasions that require high sealing performance, such as chemical, pharmaceutical, food and other industries.

3. High-pressure forged steel ball valves are manufactured using forging processes and have high strength and pressure resistance. This type of ball valve is suitable for high-pressure pipeline systems and is often used in chemical equipment, oil refining equipment, natural gas transmission pipelines, etc. Its compact structure, reliability and durability make it an ideal choice for high-pressure fluid control.

4. Special high-pressure ball valves for oxygen-containing media are ball valves designed and manufactured for oxygen, liquid oxygen and other media containing oxygen components. The material, sealing structure, and fireproof design of this ball valve all comply with relevant standards and requirements, ensuring safe and reliable operation in an oxygen environment. It has important application value in aerospace, medical, bioengineering and other fields.

5. High-pressure electric ball valve refers to a ball valve driven by an electric actuator, which can realize remote control and automatic operation. They are usually used in large fluid control systems and have the characteristics of fast response and precise control. They are suitable for occasions that require frequent switching and precise adjustment. It is widely used in chemical, energy, water treatment and other industries.

In addition, according to different application requirements, there are a variety of special high-pressure ball valves to choose from, such as explosion-proof high-pressure ball valves, low-temperature high-pressure ball valves, etc.
