Examine the valve body, stem, and flanges for cracks, corrosion, or leaks. Early detection prevents failures.

Apply manufacturer-approved lubricants to stems, packing, and moving parts for smooth operation.

Remove dirt, scale, and debris from internal and external surfaces to ensure proper valve function.

Check all bolts, nuts, and packing. Tighten or replace components as necessary to prevent leaks.

Operate the valve fully to verify smooth movement, proper sealing, and absence of unusual resistance or noise.

Identify and resolve issues like stiffness, leakage, noise, or misalignment promptly.
