Ball Valve Suppliers & Manufacturers in China

Ball valves are the workhorse of flow control: a bored sphere turns a quarter to stop or start media, which makes them fast to operate, low-torque and suitable for on/off isolation rather than fine throttling. Buyers comparing Chinese ball valve suppliers usually start with the body material — stainless steel for water, chemicals and food lines, carbon steel for general industrial service, brass for smaller utility connections — then the port design (full bore for pigging and low pressure drop, reduced bore for compact, lower-cost installations), the connection (threaded, flanged, welded or clamped), and the seat and seal materials that determine temperature and chemical compatibility.

Pressure class, actuation (manual lever, electric or pneumatic) and the applicable test standard matter just as much. On this page you can filter ball valve manufacturers by these practical criteria, open a product to see the parameters each supplier has published, and contact the exhibitor directly to request drawings, material certificates or a quotation.

Visiting the Wenzhou valve show in May 2027 lets you compare samples side by side and discuss lead times and OEM terms in person. Pre-register for a free badge and plan your shortlist before you travel.
