1. General Information
The DGV10 F4 Resilient Seated Gate Valve is designed for use in water distribution networks, water treatment plants, and other applications requiring reliable shut-off. Proper installation is essential to ensure safe operation, long service life, and leak-free performance.
2. Safety Precautions
Installation must be performed by qualified personnel only.
Ensure compliance with all local safety regulations and standards.
Wear appropriate personal protective equipment (PPE).
Confirm that the pipeline is depressurized and drained before installation.
3. Pre-Installation Checklist
Inspect the valve for any visible damage during transport or storage.
Check that the valve type, size, and pressure rating match the system requirements.
Verify that the valve is clean and free from debris.
Confirm that the pipeline ends are properly aligned and free from burrs or sharp edges.
Ensure sufficient space is available for operation and maintenance.
4. Installation Procedure
Positioning: Install the valve in the correct flow direction as indicated by the arrow on the valve body. The valve can be installed in horizontal or vertical pipelines, with the spindle oriented vertically upward for optimal performance.
Pipeline Preparation: Ensure the pipeline is clean and free from dirt, sand, or foreign particles. Use proper gaskets suitable for the medium and operating conditions.
Mounting the Valve: Align the valve with the pipeline flanges. Insert bolts and tighten them crosswise in gradual steps to ensure even compression of the gasket. Do not use excessive force that may damage the valve body or flanges.
Operational Check: Open and close the valve fully to confirm smooth operation. Ensure the valve closes tightly without leakage.
5. Post-Installation
Slowly pressurize the system and check for leaks around the connections.
If leakage is detected, depressurize and re-tighten the bolts.
Record the installation details for documentation.
Proper maintenance extends the service life of the valve and ensures reliable performance. Follow the guidelines below:
1. Routine Operation
Operate the valve (open/close) periodically to prevent seizure and buildup of deposits on the sealing surfaces.
Avoid using the valve for throttling, as it is designed for on/off service.
2. Inspection Schedule
Monthly: Check for external leaks around body joints, stem packing, and flange connections.
Quarterly: Operate the valve fully open and fully closed to verify smooth operation.
Annually: Perform a detailed inspection including seals, stem, and coating condition.
3. Lubrication
If applicable, lubricate the stem nut or gearbox according to manufacturer’s recommendations.
Ensure moving parts remain free of dirt and corrosion.
4. Seal and Gasket Replacement
Replace stem seals, O-rings, and gaskets if leakage or wear is observed.
Always depressurize and drain the pipeline before performing any maintenance work.
Only use original spare parts to guarantee compatibility and reliability.
5. Cleaning
Keep the exterior of the valve clean to prevent corrosion.
In aggressive environments, consider applying additional protective coating or insulation.
6. Storage and Spare Parts
Store spare parts in a dry, clean environment, away from direct sunlight.
