2. Safety Information and Precautions
General Precautions
- This valve is designed for manual operation only. Do not use tools to extend the handle for additional leverage.
- Ensure the working pressure does not exceed PN16.
- Confirm compatibility of the valve material with the working medium before installation.
- Do not use the valve in systems exceeding the recommended temperature range.
- Avoid sudden pressure surges that may damage internal sealing components.
WARNING! EU Market Reference
This product may be used in gas systems. Improper installation may result in gas leakage, fire, or explosion. Installation must be carried out by qualified professionals in accordance with applicable EU and national standards.
- Do not exceed the rated pressure PN16.
- Before maintenance, ensure the pipeline system is fully depressurized.
- Keep out of reach of children.
- Proper disposal: Follow WEEE directives and local regulations for metal and mechanical component recycling where applicable.
Note: The above warning information is for reference only. Final warning language must comply with the official language requirements of the destination EU country.

4. Setup and Installation
Preparation
- Ensure the selected valve type (T or L) matches the intended flow control design of the pipeline.
- Confirm that the thread size corresponds to the pipe specification.
- Shut off upstream pressure before installation.
- Apply appropriate thread sealing tape or sealant to the male pipe threads.
Installation
- Install the valve using appropriate tools.
- Avoid excessive torque to prevent thread damage.
5. Operation
Handle Rotation and Flow Control
Figure 3: T-Type and L-Type Three-Way Ball Valves
- For T-type valves: Rotate the handle up to 180 degrees to control flow distribution.
- For L-type valves: Rotate the handle 90 degrees to switch flow direction.
- Ensure the handle is fully positioned at the desired stop point.
Data Reading (Flow Path Indication)
The handle direction indicates the internal ball port orientation. Align the handle with the desired flow path. Verify flow condition by checking downstream output.

6. Storage and Maintenance
Storage
- Store the valve in a dry, ventilated environment away from corrosive substances.
- Keep protective caps on threads before installation to prevent contamination.
Maintenance
- Periodically inspect for leakage, corrosion, or handle looseness.
- If leakage occurs, depressurize the system before inspection or replacement.
- Clean the external surface with a dry or slightly damp cloth. Do not use aggressive chemical cleaners.
7. Troubleshooting
This section provides guidance for common issues you might encounter with your three-way ball valve.
| Problem | Possible Cause | Solution |
|---|---|---|
| Leakage from threads | Improper thread sealant, damaged threads, insufficient tightening. | Depressurize system. Reapply thread sealant (tape or compound) and re-tighten. Inspect threads for damage. |
| Valve not fully closing/opening | Debris in valve, damaged ball/seat, handle misalignment. | Depressurize system. Inspect for obstructions. Check handle alignment with flow path indicators. |
| Stiff handle operation | Lack of lubrication, internal corrosion, excessive pressure. | Ensure operating pressure is within PN16. Inspect for corrosion. (Note: Ball valves are generally maintenance-free for lubrication). |
8. User Tips
- Verify Valve Type: Always double-check that you have received the correct T-type or L-type valve before installation to ensure it matches your intended flow configuration.
- Thread Sealing: For a leak-free connection, generously apply high-quality PTFE thread seal tape or pipe sealant to the male threads before assembly.
- Avoid Overtightening: While a secure connection is important, overtightening can damage threads or the valve body. Use appropriate tools and apply firm but not excessive torque.
