5. Installation Instructions
5.1 Preparation
- Ensure the pipeline is clean and free of debris.
- Verify that the valve specifications match the application requirements.
- Check the electric actuator for proper configuration and voltage compatibility.
5.2 Alignment
- Align the valve with the pipeline flanges.
- Ensure proper alignment to avoid stress on the valve body and flanges.
5.3 Bolting
- Secure the valve using appropriate bolts and nuts.
- Tighten bolts evenly in a crisscross pattern to ensure a proper seal.
5.4 Electrical Connection
- Connect the electric actuator to the power supply according to the manufacturer's wiring diagram.
- Ensure all electrical connections are secure and properly insulated.
5.5 Testing
- Test the valve for proper operation using the electric actuator.
- Check for leaks and ensure the valve opens and closes smoothly.
6. Maintenance
6.1 Regular Inspection
- Periodically inspect the valve and actuator for signs of wear or damage.
- Check the gate, seals, and stem for any abnormalities.
6.2 Seal Replacement
- Replace the seals if leakage is detected.
- Use compatible seal materials for the specific media and operating conditions.
6.3 Actuator Maintenance
- Follow the actuator manufacturer's maintenance guidelines.
- Ensure the actuator operates smoothly and is free from debris.
6.4 Gate Inspection
- Inspect the gate for wear and replace if necessary.
- Ensure the gate moves freely without obstruction.
7. Safety Precautions
- Ensure the pipeline is depressurized before performing any maintenance.
- Use appropriate personal protective equipment (PPE) when handling the valve.
- Follow all relevant safety standards and guidelines.
- Ensure all electrical connections are de-energized before maintenance.
8. Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Valve does not open/close | Obstruction in the gate area | Inspect and clean the gate area |
| Leakage through the seal | Worn or damaged seal | Replace the seal |
| Actuator not responding | Electrical issue or actuator fault | Check electrical connections and actuator status |
| Difficulty in manual operation | Debris or damage in the stem or gate | Clean and inspect the stem and gate |
