The process of globalization has entered a period of deep adjustment, and trade data has become a key support for decoding industry trends, seizing market opportunities, and reshaping the business landscape.
In the context of increasingly fierce international competition and accelerating iterations of trade rules, cutting-edge, professional, and systematic business analysis capabilities have become the core elements for companies to seize opportunities.
Customs data, as the “gene map” of international trade, can accurately analyze supply chain dynamics and market demand. With the help of professional technology platforms, companies can build a full-link decision-making system, realize the leap from passive response to proactive prediction, and lay a solid foundation for the high-quality development of global trade.
The recently released report takes the six-year long-term data from 2020 to 2025 as the vertical axis and the world’s major countries and regions as the horizontal axis, establishing a three-dimensional, comprehensive and in-depth trade data research system.
The report tracks the development changes of China’s import and export trade of check valve products throughout the process, focusing on the core export market, deeply revealing the status, advantages and development potential of Chinese products in the global supply chain; drawing a panoramic view of the competitive landscape of domestic exporters, clearly showing the industry’s competitive situation; simultaneously unlocking overseas core purchaser resources, and building an efficient and accurate supply and demand data bridge for the industry.
The check valve, also known as check valve, one-way valve, reverse flow valve and back pressure valve, is an automatic valve that relies on the flow of the medium itself to automatically open and close the valve disc to prevent the backflow of the medium.
Its core working principle is based on the characteristics of fluid dynamics. When the medium flows in the forward direction, the pressure pushes the valve disc to open to ensure the smooth passage of the fluid; once the medium stops flowing or a reverse flow trend occurs, the valve disc will quickly close with the help of its own weight or spring, blocking the return flow path from the source, and building a solid defense line for the stability of the fluid delivery system.
The classification system of check valves is rich, and different classification methods correspond to differentiated structural characteristics and application scenarios.
According to the structural form, it can be divided into lift check valve and swing check valve.
The valve disc of the lift check valve slides vertically along the center line of the valve body and has excellent sealing performance. It is suitable for small and medium-diameter pipelines with sufficient installation space and strict sealing requirements. The swing check valve adopts the opening and closing method of the valve disc rotating around the axis and has small flow resistance. It is widely used in large-diameter pipelines and can better adapt to large flow conditions.
According to the installation method, there are wafer check valves and flange check valves.
The wafer check valve has a compact structure and is light in weight. The valve is clamped between two pipe flanges with bolts. It is easy to install and is suitable for pipeline systems with limited space or that require quick installation. The flange check valve is firmly connected to the pipeline through the flange. It has high connection strength and strong sealing stability. It is mostly used in high pressure, high temperature and other working conditions that require extremely high reliability.
According to material, check valves can be divided into cast iron check valves, brass check valves, stainless steel check valves, carbon steel check valves and forged steel check valves.
Cast iron check valves are low-cost and suitable for general low-pressure and normal-temperature water medium transportation scenarios; brass check valves have strong corrosion resistance and are more common in small-diameter pipelines in civil buildings; stainless steel check valves, with their excellent corrosion resistance and high temperature resistance, are widely used in industries such as chemicals and food that have strict requirements on medium cleanliness and working conditions; carbon steel and forged steel check valves have high strength and high pressure resistance, and are the core choices for high-pressure industrial pipelines such as oil and natural gas.
In recent years, the global check valve import market has shown a trend of steady expansion, and the trade scale has continued to rise.
Data show that the global import value of check valves in 2019 was US$3.306 billion, which has increased to US$3.787 billion by 2024, with a compound annual growth rate of 2.75% during the period.
Judging from the latest released data from some countries in 2025, the import demand for check valves in major markets remains strong, with imports in many countries exceeding the US$100 million mark.
Driven by the dual drive of policy guidance and market demand, China’s check valve industry has entered a rapid development track, formed a relatively prominent scale advantage, and its status in the global industrial structure continues to rise.
From 2019 to 2025, China’s check valve export volume has steadily increased from 2.146 billion sets to 2.319 billion sets, and the export value has jumped from US$485 million to US$736 million.
It is estimated that the compound annual growth rate of export quantity and value during this period reached 1.30% and 7.20% respectively. The growth rate of export value was significantly higher than the quantity growth rate, which fully reflected the increased added value and competitiveness of China’s check valve products in the international market.
From the perspective of export flow, the overseas market layout of my country’s check valves shows distinct regional concentration characteristics.
In 2025, the five major export destinations, the United States, Russia, Indonesia, Vietnam, and Thailand, will account for 33.49% of my country’s total check valve exports, becoming the core force supporting the industry’s overseas expansion.
In the future, with the continuous improvement of industrial innovation capabilities and the further release of market demand, China’s check valve industry is expected to continue to consolidate its advantages in global competition and contribute more Chinese solutions to the global fluid control field.
