Step 1: Visual Inspection
Check the valve body, stem, and flanges for corrosion, wear, leaks, or cracks. Early detection prevents costly failures.
Step 2: Lubrication
Apply manufacturer-approved lubricants to moving parts and stems to reduce friction and ensure smooth operation.
Step 3: Cleaning
Remove dirt, scale, and debris from internal and external surfaces to prevent operational issues.
Step 4: Tightening & Packing Check
Ensure all bolts, nuts, and packing are properly tightened. Replace worn packing to prevent leaks.
Step 5: Functional Testing
Operate the valve fully to verify smooth operation, proper sealing, and absence of unusual resistance or noise.
Step 6: Troubleshooting
Identify and correct issues such as stiffness, leakage, noise, or misalignment immediately.
