The countries with advanced vacuum valve technology in the world mainly include Russia, the United States, France, the United Kingdom, Germany, Japan, etc. From the early 20th century to the present, the varieties and specifications of vacuum valves in these countries have developed rapidly. Major vacuum equipment manufacturers in the world, such as Balzais, Raybold Hylas, Western European Nuclear Center and German Institute of Electronic synchrotron, are all professional manufacturers of vacuum valves and can develop various vacuum valves according to international standards.

1、 Development of Vacuum Valves Abroad
The countries with advanced vacuum valve technology in the world mainly include Russia, the United States, France, the United Kingdom, Germany, Japan, etc. From the early 20th century to the present, the varieties and specifications of vacuum valves in these countries have developed rapidly. Major vacuum equipment manufacturers in the world, such as Balzais, Raybold Hylas, Western European Nuclear Center and German Institute of Electronic synchrotron, are all professional manufacturers of vacuum valves and can develop various vacuum valves according to international standards.
Currently, among various vacuum systems abroad, vacuum plug valves are widely used due to their maximum conductivity, simple structure, and reliable performance. Due to the complex structure, short lifespan, and poor performance reliability of all metal sealed gate valves, their application range is limited. Therefore, unless all metal valves are used to ensure the performance requirements of the entire vacuum system, usually fluorine rubber sealed plug-in valves are used. For example, vacuum deposition machines, ion implantation machines, various surface physics test instruments and large accelerators all use the gate valve sealed with fluororubber as the main valve. In addition, another characteristic of vacuum valves used abroad is that the main driving forms are manual, pneumatic, and electric, with the pneumatic form being the most widely used.
2、 Development of Vacuum Valves in China
The well-known domestic vacuum valve manufacturers are Ningbo Instrument Valve Factory, which has a history of over 60 years in vacuum valve manufacturing. The vacuum valves produced include vacuum plug valves, vacuum baffle valves, vacuum ball valves, vacuum butterfly valves, vacuum inflation valves, vacuum differential pressure valves, vacuum solenoid valves, vacuum diaphragm valves, vacuum fine adjustment valves, etc. There are over 30 varieties and 400+models, which can fully meet the needs of various enterprise customers, The process level has reached the level of foreign countries, and has been widely used in electronics, semiconductors, integrated circuits, vacuum measurement, leak detection, ion beam, electron beam, laser, controllable thermonuclear reaction, aerospace and other fields. These valves are advanced in performance, stable and reliable in operation, ensuring the normal operation of these devices, marking that China's vacuum valves have a fairly high level of technology.
3、 Development prospects
In the future, the development of vacuum valves should pay attention to the following issues.
1. Attention should be paid to the issue of updating and upgrading vacuum valves. If early vacuum valves were found to have complex structures and inconvenient operations, which would cause inconvenience to the operation of vacuum devices, we hope to replace them with vacuum valves of similar specifications. Early manual vacuum valves can be replaced with electric or pneumatic vacuum valves to achieve automated operation of the vacuum system.
2. Energy conservation requires strengthening the research and development of energy-saving valves. Develop a new energy-saving vacuum valve using a combination of new sealing materials and electromagnetic driving principles.
3. The research and development of a large hand and electric dual purpose high ultra-high vacuum plug valve for enhancing the vacuum performance. Currently, there are several types of valves produced in China, including CC type (manual), CCD type (electric), CCQ type, etc. However, valves with diameters above DN500 are weak links. Electric valves are important components for achieving automatic control of vacuum systems. Optoelectronic technology should be utilized to improve the current situation

Ningbo Instrument Valve Factory Conducts Outdoor Expansion Training for Employees


On the morning of May 22, 2022, facing the booming sunrise and accompanied by laughter, the one-day outdoor expansion activity of Ningbo Instrument Valve Factory was kicked off at Jiuchengyan Outdoor Expansion Training Base. All participants were divided into three groups, and a team leader and a deputy team leader were recommended and selected from their respective teams. After everyone gathered their ideas, they developed a highly creative team name and resounding slogan: Flame Team, Star Dream Team, and Surpass Team. This slogan is not just a slogan, but will also lead everyone to constantly strive and strive for it in the upcoming expansion training and competition.
