1. General Information
The DGV14 Service connection valve is designed specifically for direct-bury installation in service lines, requiring a secure and reliable connection between the main line and the user. Proper installation is essential to ensure safe operation, long service life, and leak-free performance of this Underground Valve.
2. Safety Precautions
Installation must be performed by qualified personnel only.
Ensure compliance with all local safety regulations and standards, particularly those concerning below-grade work.
Wear appropriate personal protective equipment (PPE).
Confirm that the main pipeline is depressurized and drained before tapping or connecting the water service valve.
3. Pre-Installation Checklist
Inspect the Service connection valve for any visible damage during transport or storage.
Check that the valve type, size, and connection method (e.g., compression, threaded) match the system requirements.
Verify that the valve is clean and free from debris.
Confirm that the pipeline ends are properly cut, deburred, and aligned for a tight connection.
Ensure sufficient access is available for the operating key or wrench after backfilling.
4. Installation Procedure
Positioning: Install the DGV14 Service connection valve in the designated connection point, typically a tap on the main line or directly on the service pipe.
Pipeline Preparation: Ensure the pipeline is clean. Use the appropriate sealing compounds, compression fittings, or threading techniques suitable for the pipe material and the Service connection valve.
Mounting the Valve: Securely join the valve to the pipe ends. For compression fittings, tighten the nuts evenly to the manufacturer’s specified torque to achieve a watertight seal, avoiding overtightening which could damage the valve or pipe.
Operational Check: Before final backfilling, test the Underground Valve by fully opening and closing it using the appropriate key to confirm smooth operation.
5. Post-Installation
Slowly pressurize the system and check for leaks around the connections.
If leakage is detected, depressurize and re-tighten the connections or verify the gasket/seal integrity.
Backfill: Carefully backfill the trench, ensuring the water service valve is properly bedded and protected from heavy loads, typically using sand or fine-grained soil around the valve body before compaction.
Record the installation details for documentation.
Proper maintenance extends the service life of the DGV14 Service connection valve and ensures reliable performance as a critical component in your network. Follow the guidelines below to maximize the lifespan of this Underground Valve:
1. Routine Operation
Operate the Service connection valve (open/close) periodically using the appropriate key to prevent seizure and buildup of deposits on the internal mechanism.
Avoid using the water service valve for throttling or flow regulation, as it is strictly designed for on/off isolation service.
2. Inspection Schedule
Quarterly: Operate the Service connection valve fully open and fully closed to verify smooth operation and ensure the key engages correctly with the operating nut.
Annually: Check the surrounding ground for any signs of water seepage or soil settlement which could indicate a leak from the buried Underground Valve.
3. Protection and Lubrication
The DGV14 Service connection valve is designed to be maintenance-free regarding lubrication due to its robust materials.
Ensure the operating nut and key access point remain free of dirt, debris, and corrosion to guarantee ease of operation.
4. Seal and Connection Check
If persistent leakage is detected at the connections, depressurize and drain the pipeline before carefully excavating the Underground Valve area for inspection.
Only use original manufacturer spare parts if internal seals or O-rings of the water service valve need replacement following excavation.
5. Cleaning
Keep the key access point clean to ensure that the operating tool can be fully and securely seated on the Service connection valve stem nut.
Ensure that the soil or backfill material used around the Underground Valve is free of large stones or debris that could damage the body coating.
6. Storage and Spare Parts
Maintain an operating record of all functional checks and any maintenance performed on the water service valve units.
If valves are stored before installation, keep them in a dry, clean environment, protected from direct sunlight or aggressive chemicals.
