Installation Instructions
Preparation: Ensure the pipeline is clean and free from debris. Check flange connections for 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 to ensure even pressure.
Inspection: Verify that the valve operates smoothly by manually opening and closing it. Ensure there are no obstructions.
Operation Guidelines
- Opening: Rotate the handwheel counterclockwise to open the valve.
- Closing: Rotate the handwheel clockwise to close the valve.
- Flow Control: Adjust the handwheel to regulate flow as needed.
Maintenance
- Regular Inspection: Check for signs of wear or damage. Ensure the handwheel and stem are lubricated.
- Seal Replacement: Inspect seals periodically and replace if necessary to maintain zero 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.
