- Identify leaks, corrosion, and mechanical failure
- Inspect body, disc, seat, stem & bonnet
2. Disassembly
- Strip valve to component level
- Remove seized bolts & corroded components
- Prepare for cleaning and machining
3. Cleaning & Surface Preparation
- Mechanical cleaning
- Chemical cleaning (if needed)
- Rust removal
- Sandblasting or shot blasting
4. Machining & Repair
- Seat lapping & machining
- Stem straightening or replacement

- Rebuilding damaged body sections
- Resurfacing sealing faces
5. Replacement of Components
We replace all critical components with compatible materials:
- Seals (EPDM, NBR, Viton, silicone)
- O-rings
- Seats
- Bushings
- Bearings
- Gaskets
- Bolts & nuts
6. Coating & Corrosion Protection

- Polyurethane lining
- Chemical-resistant coatings (optional)
7. Reassembly & Testing
- Torque checks
- Pressure testing
- Functional opening/closing test
- Leakage test
- Final inspection & QA report
