산업용 밸브는 산업용 장비의 중요한 부분입니다.. 산업용 밸브는 주로 유체의 흐름을 제어하는 장치를 말합니다., 압력, 흐름 채널 영역의 크기를 변경하여 흐름 방향.
이는 유체 이송 시스템의 제어 구성 요소입니다.. Their functions include opening and closing, regulating, throttling, 등. Industrial control valves are mid-to-high-end products among industrial valve products.
Control valves are control components in fluid conveying systems, with functions such as cutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion, or overflow pressure relief.
Industrial control valves are mainly used for process control in industrial equipment and belong to the instrumentation, metering, and automation industries. Control valves are similar to robot arms in the process of realizing industrial automation.
They are the final control elements for changing process parameters such as medium flow, 압력, 온도, and liquid level. Because they are terminal actuators in industrial automation process control systems, control valves are also called “액추에이터” and are one of the core components of intelligent manufacturing.
Control valves are composed of two main assemblies: valve body assemblies and actuator assemblies (or actuator systems), which are divided into four major series: single-seat series control valves, double-seat series control valves, sleeve series control valves, and self-actuated series control valves.
Unlike manual valves, control valves are general fluid mechanical equipment and are industrial automation instruments that achieve automatic control and precise flow regulation under complex and harsh working conditions. Control valve technology involves related cross-disciplinary technologies such as material engineering, mechanical design and manufacturing, fluid mechanics, control science and engineering, measurement technology and instrumentation, and is widely used in industrial fields such as petroleum, 천연 가스, 화학 산업, 야금, 전력, nuclear industry, 항공우주, military industry, 조선, marine engineering, 환경 보호, 및 의약품.
Development history of industrial control valve industry
The development of industrial control valves is closely related to the development of industrial production processes. 현재, in order to adapt to the special requirements of new industrial sectors or processes, modern industry has put forward higher requirements for control valves, such as more stable quality, safer operation, and stricter environmental protection standards. Some specific industries even put forward bubble-level requirements for the hard seal and emergency cut-off leakage rate of valves.
With the continuous advancement of science and technology, the market demand for product functions is increasing, the technical level of China’s control valve industry is constantly improving, and intelligent control valve products with automatic control technology are gradually emerging, continuously realizing the technical iteration from low-end products to mid-to-high-end products. As the world’s largest manufacturing country, China’s diversified industrial sectors such as oil and gas, 화학, 전기, food and beverages all have a large demand for control valves. 게다가, the Chinese government’s infrastructure investment and industrial modernization plans, such as the “new infrastructure”, have also provided further growth momentum for the control valve market.
China has made significant progress in science and technology, especially in automation, control systems and sensor technology. These technological advances have provided Chinese manufacturers with more opportunities and conditions to develop and produce industrial control valves with high performance. The demand for industrial control valves in the Chinese market continues to grow, especially with the renewal and replacement of some old equipment. Faced with huge market demand, Chinese companies have greater motivation and motivation to increase the localization rate.
With the continuous improvement of the innovation capabilities of Chinese companies, more and more Chinese companies have begun to conduct research and development and innovation in the field of industrial control valves. Innovation helps to improve product quality and performance and enhance the advantages of Chinese control valves in market competition.

Main downstream operation of the control valve industry
Control valves can be divided into two categories: gas control and liquid control according to the different control media, and can be further subdivided into several professional fields such as water control, refrigerant control, fuel control, air control, and gas control according to the media. Due to their professional characteristics, control valve products are of various types and have many applications.
그러므로, the development of the terminal products they support directly affects the technical development trend and market development of control valves. The main application industries of control valves are petrochemicals, 경공업, 발전, 석유와 가스, and steel and metallurgy.
