Industrial Valve Overhauling & Services
Description
Industrial Valve Overhauling Services help keep industrial valves reliable, safe and ready for continuous operation. Our industrial valve overhauling, repair, maintenance and testing services are designed to identify wear, leakage, damaged components and operating issues before they cause unexpected downtime.
Industrial valves are critical components of process plants, pipelines and utility systems. Regular inspection and professional servicing can help identify wear, leakage and operating problems before they lead to unexpected downtime.

Our Valve Overhauling Process
Our industrial valve overhauling process begins with a detailed inspection and documentation of the valve condition.
1. Inspection
The valve is inspected for visible damage, corrosion, leakage, wear and operating problems.
2. Dismantling
The valve is carefully dismantled so that individual components can be inspected.
3. Cleaning
Components are cleaned to remove deposits, dirt, corrosion products and other contaminants.
4. Component Inspection
Critical components such as the body, bonnet, stem, disc, ball, plug, seats, packing and gaskets are inspected.
5. Repair or Replacement
Damaged or worn components are repaired or replaced depending on their condition and the customer’s requirements.
6. Lapping, Grinding or Machining
Where required, valve seats and other components may be restored through suitable machining, lapping or grinding operations.
7. Reassembly
The valve is assembled using suitable components, seals, packing and gaskets.
8. Testing
The serviced valve is tested according to the agreed testing requirements and applicable standards.
9. Final Inspection
The completed valve is inspected and prepared for dispatch or installation.
