Electric Three-Way Flanged Ball Valve is a Kailing three-way automated ball valve package. The catalog model example Q944F-16P-DN50 maps to transmission code 9 and connection code 4. Confirm L-type or T-type flow path before quotation, because the PDF shows multiple flow-path schemes for switching, mixing or diverting service.
Q944F-16P-DN50 - Q: ball valve
- 9: electric
- 4: flange
- 4: floating L type three-way
- 5: floating T type three-way
- F: PTFE
- 16: 1.6MPa catalog pressure code
- P: stainless steel 304
Flow-path confirmation
The PDF shows T-type and L-type flow diagrams. Confirm the required port switching scheme before Kailing sizes the valve and actuator package.
RFQ confirmation points
Confirm flanged size, flow path, medium, pressure, temperature, body material, seal material, actuator control mode and accessories before RFQ.

Three-way ball valve flow-path schemes from PDF page 121
| Flow type | Catalog scheme | RFQ handling |
|---|---|---|
| T type | Scheme 1 | Use the PDF flow-path diagram to confirm port switching before RFQ |
| T type | Scheme 2 | Use the PDF flow-path diagram to confirm port switching before RFQ |
| T type | Scheme 3 | Use the PDF flow-path diagram to confirm port switching before RFQ |
| T type | Scheme 4 | Use the PDF flow-path diagram to confirm port switching before RFQ |
| L type | Catalog scheme | Use the PDF flow-path diagram to confirm whether the valve is for diverting, mixing or switching |
The PDF provides diagrams rather than text arrows. JHClaw should ask the buyer to mark or describe the required port-switching scheme.
