Frequently Asked Questions (FAQ)

1. What are the main types of manual ball valves produced in China?

Chinese manufacturers commonly produce floating ball valves, trunnion ball valves, full port and reduced port ball valves, V-type ball valves, and top-entry ball valves. Each type caters to different service pressures, sizes, and flow control needs.

2. Which industries predominantly use manual ball valves from these manufacturers?

Industries include upstream and downstream oil and gas, petrochemical plants, seawater desalination facilities, offshore drilling platforms, power generation, chemical processing, and municipal water supply systems.

3. Do Chinese manual ball valve manufacturers meet international quality standards?

Yes, most leading manufacturers comply with international standards such as API 6D (pipeline valves), API 607 (fire safety), ISO 9001 (quality management), ASME, ANSI, CE, and DIN certifications, ensuring valve safety and performance worldwide.

4. How do floating ball valves differ from trunnion ball valves?

Floating ball valves rely on the ball being held snugly between two seat rings, moving slightly to seal against the downstream seat under pressure – best suited for smaller sizes and lower pressures. Trunnion ball valves have the ball anchored by a shaft (trunnion), which supports the ball and reduces torque for operation – ideal for larger valves and higher pressures.

5. Can manufacturers provide customized manual ball valves and OEM services?

Absolutely. Many Chinese manufacturers, including industry leaders like Wenzhou Leader, offer OEM and customization services, adapting valve materials, sizes, designs, and certifications to meet specific customer technical requirements and regulatory demands.
