Three-way Ball Valve

Kizi specializes in high-performance Three-way Ball Valves designed for precise medium distribution, mixing, and directional flow control in industrial pipeline systems. Built in compliance with ASME B16.34, ASME B16.5, and API598 standards, these valves combine robust construction, versatile configuration options, and reliable sealing performance to meet the needs of industries such as petrochemical, power generation, HVAC, and water treatment.

The three-way ball valve adopts a compact integrated design with a four-sided seat sealing structure, minimizing potential leakage points while ensuring smooth, efficient operation. Its low flow resistance and full-bore configuration provide high flow capacity, maintaining energy efficiency and stable performance across a wide range of pressures and temperatures. The valve body is engineered for easy installation and disassembly, with features such as an anti-blowout stem, locking device, and ISO high-platform mounting interface for automated control options.

Available in T-type, L-type, Y-type, and X-type configurations, the valve can easily divert, merge, or reverse fluid flow to suit complex piping systems. The T-type allows simultaneous flow through multiple ports, while the L-type enables directional switching between two channels—ideal for systems requiring periodic flow alternation. Each valve undergoes strict dimensional and performance testing, including sealing, pressure, and durability verification, to ensure long-term stability in demanding applications.

Kizi’s Three-way Ball Valves are manufactured from high-quality stainless steel or alloy materials, offering superior resistance to corrosion, wear, and temperature fluctuations. The lightweight structure reduces space and installation costs, making it suitable for compact system layouts. Combined with precision machining and advanced sealing technology, these valves deliver excellent reliability, minimal maintenance, and extended service life.


Suzhou Kizi Valve Co., Ltd. was established in 2008. The company mainly produces and sells various types of high-end and medium-end valves in China. Headquartered in Changshu, Suzhou, China, it is a fluid control engineering system company specializing in planning, production and inspection.
