Complete guide to maintaining your gate valves for smooth operation, longevity, and prevention of leaks or damage.

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

Apply manufacturer-approved lubricants to stems, packing, and moving parts to reduce friction and ensure smooth operation.

Remove dirt, scale, and debris from internal and external surfaces to maintain proper operation.

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

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

Address any issues such as stiffness, leakage, noise, or misalignment immediately.
