Installation Instructions
Preparation: Ensure the pipeline is clean and free from debris. Verify flange compatibility and check that the electric actuator is properly configured.
Mounting: Align the valve with the pipeline flanges. Use appropriate gaskets and bolts to secure the valve. Tighten bolts in a criss-cross pattern for even pressure distribution.
Electrical Connection: Connect the electric actuator to the power supply according to the manufacturer's specifications. Ensure all electrical connections are secure and compliant with local regulations.
Inspection: Test the actuator to ensure smooth operation and check for any obstructions in the valve.
Operation Guidelines
- Opening/Closing: Use the control system to operate the electric actuator for opening and closing the valve.
- Flow Control: Ensure the valve is fully open or closed to prevent partial obstruction and ensure optimal flow control.
- Manual Override: In case of power failure, use the manual override mechanism (if available) to operate the valve.
Maintenance
- Regular Inspection: Perform regular inspections for signs of wear or damage. Ensure the actuator and valve components are in good condition.
- Seal Maintenance: Inspect seals periodically and replace if necessary to maintain tight sealing and prevent leakage.
- Cleaning: Keep the valve and actuator clean and free from external contaminants to ensure smooth operation.
Safety Precautions
- Always disconnect the power supply before performing any maintenance or inspection.
- Use appropriate personal protective equipment (PPE) during installation and maintenance.
- Ensure all personnel are trained in valve operation and safety protocols.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Valve does not open/close | Electrical issue or obstruction | Check power supply and clear obstruction |
| Leakage | Worn or damaged seal | Replace the seal |
| Actuator malfunction | Electrical fault | Inspect connections and power supply |
