Installation Instructions
Preparation: Ensure the pipeline is clean and free from debris. Verify flange compatibility.
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.
Inspection: Verify smooth operation by manually testing the gate. Ensure there are no obstructions.
Operation Guidelines
- Opening/Closing: Operate the valve using the handwheel for opening and closing.
- Flow Control: Ensure the valve is fully open or closed to prevent partial obstruction.
Maintenance
- Regular Inspection: Check for signs of wear or damage. Ensure the gate and seal are in good condition.
- Seal Maintenance: Inspect the hard seal periodically and replace if necessary to maintain minimal leakage.
- Cleaning: Keep the valve clean and free from external contaminants.
Safety Precautions
- Always depressurize the system before performing maintenance.
- 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 | Obstruction or mechanical issue | Clear obstruction and inspect mechanism |
| Leakage | Worn or damaged seal | Replace the seal |
| Difficult operation | Mechanical wear | Lubricate and inspect for wear |
