Helping you understand Chinese valve manufacturers/factories

1. How many valve manufacturers/ factories are there in China?

According to rough estimates, as of 2025, there were approximately 13,000 valve manufacturing plants in China, of which about 2,500 had annual revenue exceeding 20 million yuan. If we include enterprises engaged in valve-related businesses in a broader sense, such as trade, distribution, and supporting services, the total number of registered enterprises nationwide is approximately 1.878 million, indicating a vast industrial ecosystem.

2. Industry Structure: Large industry, small enterprises, fragmented, and with low concentration.

The CR10 (top 10 companies’ market share) is below 30%, far lower than mature markets in Europe, America, and Japan. By 2025, the market share of leading companies (such as Neway Valve and CNNC Technology) is gradually increasing, and the CR10 is expected to exceed 30%, but industry consolidation is still in its early stages, with small and medium-sized enterprises dominating the structure.

Small and micro enterprises (annual output value < 50 million yuan): accounting for over 80%, mainly small factories and family businesses, with products concentrated in low-pressure and general-purpose valves. Medium-sized enterprises (annual output value of 50 million-500 million yuan): accounting for approximately 15%, possessing certain R&D capabilities, mainly focusing on mid-to-high-end general-purpose valves. Large leading enterprises (annual output value > 500 million yuan): only about 20 companies, such as Neway Valve, Jiangsu Shentong, and CNNC Technology, focusing on high-end fields such as nuclear power, oil and gas, and LNG, with high technological barriers and strong competitiveness in overseas markets.

3. The industry has a detailed division of labor and a high degree of supply chain cooperation.

Most factories focus on a specific niche, manufacturing a few types of valves in which they have an advantage. They typically base their products on a main product, then combine it with several other types of valves. For example, some mainly produce ball valves, some butterfly valves, some steam traps, and some valves made of special materials. Others mainly produce castings, sealing materials, and special component processing, relying on a high degree of cooperation and collaboration within the supply chain to achieve rapid production and delivery.

Even leading valve companies do not produce all types of valves; some of their products may be outsourced to other factories. Therefore, it is a misconception to think that finding a factory will allow you to manufacture all the products you want.
