Kailing three-way ball valve packages use the ball valve ordering system with structure code 4 for L-type three-way and 5 for T-type three-way flow paths. Use this page to confirm flow path, connection type, actuator type, pressure, material and accessory requirements.

Choose L-port or T-port first
The PDF shows separate L-type and T-type flow-path schemes. Before RFQ, confirm whether the three-way valve is for diverting, mixing or switching, and mark the required flow scheme.
Do not reuse straight-through pressure notes blindly
The three-way page lists pneumatic air supply as 0.3-0.8MPa and medium pressure as 0-4.0MPa. Keep this product family separate from straight-through ball valve pages.
RFQ confirmation points

Frequently Asked Questions
- FAQ What is the key difference from a standard ball valve RFQ?
A three-way ball valve RFQ must confirm L-port or T-port flow path and the intended switching logic, not only size and material. - FAQ Can Kailing quote pneumatic and electric three-way versions?
Yes. The catalog includes pneumatic AT actuator packages and electric KLST actuator packages for three-way ball valves. - FAQ Are catalog dimensions final production drawings?
No. Use the tables as reference and confirm final drawings by exact model, connection and selected actuator.
