Hydraulic valve is an automated component operated by pressure oil, which is controlled by the pressure oil of the pressure distribution valve. It is usually used in combination with electromagnetic pressure distribution valves and can be used to remotely control the on-off of oil,gas,and water pipeline systems in hydropower stations. Commonly used in oil circuits such as clamping, control, and lubrication. There is a distinction between direct action type and pilot type, with pilot type being commonly used. The components used to control liquid pressure, flow rate, and direction in hydraulic transmission. The one that controls pressure is called a pressure control valve, the one that controls flow is called a flow control valve, and the one that controls on, off, and flow is called a directional control valve.
According to the "2023-2028 Deep Analysis and Development Planning Consulting Research Report on the Hydraulic Valve Industry Market" released by China Research Puhua Industry Research Institute, it is shown that:
The emergence of hydraulic valves on a global scale can be traced back to the Spring and Autumn Period and Warring States period in China, as well as the ancient Egyptian and Greek civilizations. However, it is widely recognized that hydraulic valves first appeared in the ancient Roman period. The ancient Romans developed a quite complex water system for crop irrigation, using plug valves and plunger valves, and using check valves to prevent reverse flow of water. During the Renaissance, hydraulic valves were also used in ditches, irrigation projects, and other large-scale hydraulic system projects designed by artist and inventor Leonardo da Vinci. After World War II, due to the need for post-war reconstruction in many countries, as well as the development of various special materials, including aggregated materials, smooth materials, stainless steel, and cobalt based hard alloys, outdated plug valves and butterfly valves were newly used, and ball and diaphragm valves based on the evolution of plug valves were rapidly developed.
As of now, with the development of industry and technology, hydraulic valves have already penetrated into various industries. From construction industry to electronic industry, from petrochemical industry to space industry, hydraulic valves play an important role. From the perspective of market distribution, the global hydraulic valve market is mainly occupied by Europe, the United States, China, and Japan. Although China's hydraulic technology started relatively late, the rapid development of market scale has played an important driving role in the global hydraulic industry.
According to the International Fluid Power Association, by 2021, China has become the world's largest hydraulic market, with its market share jumping from 26.93% in 2010 to 36.90%. At the end of the 19th century and the beginning of the 20th century, the working medium of hydraulic transmission was changed from water to oil, achieving a breakthrough in the quality of hydraulic technology and initiating the development process of modern hydraulic technology. Afterwards, with the continuous maturity of technology, hydraulic technology gradually popularized from military to civilian industrial sectors. The hydraulic components industry in foreign countries has a long history of development and is relatively mature. It has formed a group of internationally renowned enterprises, such as Bosch Rexroth, Kawasaki Heavy Industries, Parker Hannifin, Eaton Hydraulic, etc. The global hydraulic industry has entered a relatively stable and mature stage. The market size of the hydraulic valve industry is highly correlated with a country's economic output and industrialization level. The United States, China, Japan, Germany, and France are the top five countries in global hydraulic sales.
Analysis of the Current Market Situation of China's Hydraulic Valve Industry
The technological innovation in China's hydraulic industry, based on the introduction of advanced foreign technologies, has narrowed the gap with foreign advanced levels through digestion, absorption, and innovation, and can be basically applied to the matching of major equipment in China; However, in the field of high-end equipment, there is still a certain gap with the advanced level of foreign countries.
Due to the fact that hydraulic valves belong to mechanical basic components, and China's mechanical basic component industry lacks systematic research and application of materials, heat treatment processes, and other technologies, investment in basic common technology research and development and experiments is small and scattered, and basic technology is weak, resulting in high failure rates, short service life, and poor reliability of hydraulic products. There is a significant gap compared to the advanced level of foreign countries. The performance of hydraulic products is closely related to basic science and technology such as materials and heat treatment, and materials affect the performance and anticorrosion performance of hydraulic component friction pairs; And heat treatment can refine the material structure, improve material hardness and mechanical properties; Materials and heat treatment have a significant impact on the performance of hydraulic components, and outdated materials and heat treatment processes seriously affect the technological innovation of the hydraulic industry.
Market Development and Forecast of Hydraulic Valve Industry in China
According to market research data analysis, the market size of China's hydraulic valve industry showed an annual growth trend from 2019 to 2022. In 2022, the market size of China's hydraulic valve industry was 14.03 billion yuan, a year-on-year increase of 14.7%. Chinese hydraulic valve enterprises have gradually established their competitive advantages by increasing capital and technological investment in different segmented fields. In their respective segmented markets, they have relatively mature host supporting capabilities, stable customer base, and certain technical reserves. The gap with internationally renowned hydraulic enterprises is gradually narrowing.
Under the guidance of relevant national policies and driven by market demand, it is expected that the industry's concentration ratio will gradually increase in the future, and hydraulic valve enterprises with strong technical strength and excellent management ability will get opportunities for industry integration, and then become bigger and stronger. While promoting the overall technical level of China's hydraulic industry, it will alleviate the current situation of insufficient supply of high-end products in China. Although domestic hydraulic valve enterprises still have shortcomings compared to foreign enterprises in terms of overall strength, some hydraulic valve enterprises have continuously strengthened their talent team construction and improved their technical process level after the development process of "introduction, absorption, and innovation". In some hydraulic valve subdivision areas, they have reached international advanced levels, and their local competitive advantages are becoming increasingly prominent, gradually possessing the ability to replace imported products, It has laid a solid foundation for further expanding domestic and international markets.
Prediction of Future Development Trends in the Hydraulic Valve Industry
In recent years, the hydraulic markets in the United States, China, and Europe have shown a steady expansion trend. The future development trend of hydraulic components is as follows: towards high-performance, high-quality, high reliability, and complete system development; Developing towards environmental requirements such as low energy consumption, low noise, vibration, no leakage, pollution control, and the application of water-based media; The industry will strive to develop high integration, high power density, intelligence, mechatronics
integration, as well as light, small, and micro hydraulic components; Actively adopting new processes, materials, electronics, sensing and other high-tech technologies. Looking at the development of the industry, intelligence, energy conservation, green, and reliability are the main
trends in the future technological development of the industry.
