If you’re searching for reliable trunnion ball valve manufacturers in China, you’re in the right place. Trunnion ball valves are essential components that control the flow of liquids and gases in high-pressure pipelines.
These valves are known for their strength, tight sealing, and long-term reliability, making them indispensable in industries such as oil and gas, petrochemicals, and power generation.
This guide introduces the Top 10 trunnion ball valve manufacturers in China, providing practical insights for engineers, procurement teams, and business owners.
You’ll also learn what makes a quality trunnion-mounted ball valve manufacturer stand out and why CTGV is recognized as one of the most trusted names in this field.
What Is a Trunnion Ball Valve?
A trunnion ball valve uses a fixed ball supported by a trunnion (a mechanical anchor) that keeps it in place during operation. Unlike floating ball valves, which rely on pressure to seal, the trunnion design ensures stability under high pressure and prevents seat wear.
Key takeaways:
- The ball is anchored by a shaft (trunnion) for enhanced stability.
- Suitable for high-pressure and large-diameter pipelines.
- Commonly used in oil, gas, chemical, and power applications.

Choosing the Right Trunnion Ball Valve Manufacturer
Selecting the right manufacturer goes beyond price. Here are three main factors to consider when sourcing:
- Quality Certifications: Ensure compliance with API 6D, ISO9001, and CE standards for reliability and safety.
- Testing Capabilities: Look for manufacturers that follow EN 12266 testing, ensuring each valve passes pressure and leak tests.
- Customization and After-Sales Support: Companies like CTGV offer OEM/ODM valve customization and 24/7 engineering support, minimizing downtime and ensuring fast response times.
The Role of Resilient Seated Butterfly Valves
Although this guide focuses on trunnion ball valves, resilient seated butterfly valves are another essential component in flow control systems. These valves use an elastic rubber seat to create a tight seal, offering excellent performance for water, HVAC, and chemical industries.
CTGV also manufactures these valves with HVOF and PVD coatings for enhanced corrosion resistance and longer service life. Integrating both valve types —trunnion ball valves for high pressure and resilient seated butterfly valves for moderate pressure —ensures full system efficiency across applications.
