Setup and Installation
Proper installation is crucial for the long-term performance and safety of the valve. This valve is designed for socket weld installation.
- Preparation:
- Inspect the valve for any shipping damage or debris.
- Ensure the pipe ends are clean, free of burrs, and properly beveled for socket welding.
- Verify that the valve's material and pressure rating are compatible with the system's requirements.
- Positioning:
- Position the valve correctly in the pipeline, ensuring the flow direction (if indicated) matches the system flow.
- Support the valve adequately during welding to prevent stress on the connections.

- Welding:
- Perform socket welding according to applicable industry standards (e.g., ASME B31.1, ASME B31.3) and local codes.
- Use appropriate welding procedures and qualified welders.
- Avoid overheating the valve body during welding, which could damage internal components. Consider using heat sinks if necessary.
- Post-Installation:
- Allow welds to cool completely before pressurizing the system.
- Conduct a hydrostatic test or other appropriate leak tests to ensure weld integrity.
Operating Instructions
The Hancock Series 7000 Globe Valve is a manual valve operated by turning the handwheel.
- To Open the Valve: Turn the handwheel counter-clockwise. Continue turning until the valve is fully open or the desired flow rate is achieved. Globe valves are designed for throttling service, allowing for precise flow regulation.
- To Close the Valve: Turn the handwheel clockwise. Continue turning until the valve is fully closed and a tight shut-off is achieved. Do not overtighten, as this can damage the seating surfaces.
- Throttling: For flow regulation, adjust the handwheel to the desired position. The globe valve's design allows for good throttling characteristics.
Maintenance
Regular maintenance ensures the longevity and reliable operation of your valve.
- Periodic Inspection: Regularly inspect the valve for external leaks, corrosion, or damage to the handwheel and stem.
- Packing Gland: If stem leakage occurs, the packing gland may need to be tightened. Gradually tighten the packing nuts until the leakage stops. Do not overtighten, as this can impede stem movement.
- Cleaning: Keep the exterior of the valve clean to prevent accumulation of dirt or corrosive substances.
- Lubrication: The stem threads and packing area may benefit from periodic lubrication with a suitable lubricant compatible with the process fluid and valve materials.
- Storage: If the valve is to be stored for an extended period, ensure it is clean, dry, and stored in a protected environment to prevent corrosion.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Stem Leakage | Loose packing gland, worn packing | Tighten packing nuts gradually. If leakage persists, replace packing. |
| Valve Does Not Close Fully | Debris in valve seat, damaged disc/seat | Flush the system to remove debris. If problem persists, valve may require disassembly and inspection by qualified personnel. |
| Difficult to Operate Handwheel | Overtightened packing, stem corrosion, bent stem | Loosen packing nuts slightly. Clean and lubricate stem. If stem is bent, valve repair or replacement may be necessary. |
| External Body Leakage | Cracked body, faulty weld, loose bonnet bolts | Inspect for visible cracks or weld defects. Tighten bonnet bolts if applicable. Significant leaks may require professional repair or valve replacement. |
