Gate Valves Maintenance – Vikhroli

Step-by-step maintenance guide to ensure smooth operation, prevent leaks, and extend the lifespan of your gate valves.

Step 1: Visual Inspection

Examine the valve body, stem, and flanges for leaks, corrosion, cracks, or physical damage.

Step 2: Lubrication

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

Step 3: Cleaning

Remove dust, scale, and debris from internal and external surfaces to avoid operational issues.

Step 4: Tightening & Packing

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

Step 5: Functional Testing

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

Step 6: Troubleshooting

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

Common Problems & Solutions

  • Leakage: Tighten packing, replace gaskets, or repair valve seats.
  • Stiff Operation: Lubricate and clean moving parts.
  • Corrosion: Apply protective coatings or replace damaged components.
  • Noise: Check alignment and clean internal surfaces.

Preventive Maintenance Tips
