1. Industry Status
Market size continues to expand
The global swing check valve market size has reached US$2.3 billion (2024), and is expected to exceed US$3 billion in 2025. China's market share has increased significantly, especially in the fields of nuclear power, water treatment and chemical industry. Check valves are a core category. The Chinese market size was about 1.86 billion yuan in 2020, and is expected to exceed 3 billion yuan in 2025, with an annual compound growth rate of more than 8%. Wide range of applications
Traditional fields: petroleum, municipal water supply, chemical industry, etc. still dominate, and swing check valves are widely used due to low flow resistance and large-caliber adaptability. Emerging fields: The nuclear power industry has become a growth engine, and the demand for nuclear-grade swing check valves has surged due to high safety requirements and anti-backflow performance. The market size of nuclear power valves is expected to exceed 8.5 billion yuan in 2025. Region and competition pattern
Domestic enterprises are concentrated in industrially developed regions (such as the Yangtze River Delta and the Pearl River Delta), but the high-end market is still dominated by international brands.
The salary level of the swing check valve industry is relatively low (4.5-6K per month in Fuzhou), reflecting that the proportion of technology-intensive positions is limited and the market competition is mainly based on price.
II. Industry development trends and prospects
Technology upgrade and product innovation
Intelligence: Intelligent check valves (such as those with sensors and remote control functions) are gradually becoming popular, improving the operating efficiency and stability of pipeline systems.
New materials and processes: Nuclear-grade valves use radiation-resistant and high-temperature resistant alloy materials, and silent check valves introduce elastic seals (such as rubber/polytetrafluoroethylene) to enhance sealing.
Policy and market demand driven
The national new energy policy promotes the accelerated implementation of nuclear power projects. In 2024, 11 new nuclear power units will be added, and it is expected that more than 10 units will be added annually before 2030, directly driving the demand for nuclear-grade valves.
Environmental regulations are becoming stricter, and the demand for leak-proof and low-noise valves in water treatment, pharmaceuticals and other fields has increased, and the market share of silent check valves has expanded year by year.
Investment and Risk Tips
Opportunities: Nuclear power, intelligence and environmental protection are the investment priorities, and technology innovation companies have greater growth potential.
Challenges: Traditional valves have overcapacity and fierce competition in the low-end market; nuclear-grade valves have high technical barriers and a long R&D investment cycle.
