We assess each valve individually to determine the appropriate repair, refurbishment or replacement requirements.

Industrial Valve Overhauling & Repair Process

A systematic repair procedure is essential for restoring valve functionality and ensuring that repaired equipment is suitable for its intended application.

Our industrial valve overhauling process generally involves the following stages, depending on valve design and service scope.

1. Initial Inspection

The valve is examined to identify visible damage, corrosion, leakage, operating difficulties and other signs of deterioration. Available technical information and operating conditions are reviewed.

2. Dismantling

The valve is carefully dismantled using suitable tools and procedures. Components are separated for detailed inspection and assessment.

3. Cleaning of Components

Internal and external components are cleaned to remove deposits, dirt, rust and other accumulated material that may affect inspection or operation.

4. Component Inspection

Important components such as the body, bonnet, disc, wedge, ball, plug, stem, seat and sealing elements are examined for wear, deformation, corrosion and damage.

5. Repair and Machining

Where technically feasible, damaged or worn components may be repaired, reconditioned or machined. Components that cannot be restored to acceptable condition may require replacement.

6. Seat Lapping and Grinding

Seating surfaces may undergo lapping or grinding, where suitable, to improve contact between mating surfaces and address certain types of internal leakage.

7. Replacement of Damaged Parts

Worn seals, gaskets, packing and other components may be replaced based on inspection findings and the agreed scope of work. Material compatibility is considered before replacement.

8. Reassembly and Adjustment

The valve is reassembled using appropriate procedures. Operating mechanisms and associated components are checked and adjusted as required.

9. Testing and Final Inspection

The repaired valve undergoes the agreed inspection and testing procedures. Testing requirements depend on valve type, design, applicable standards and project specifications.

Industrial Valve Troubleshooting & Problem Rectification

Valve problems can affect plant efficiency, process stability and equipment safety. Identifying the actual cause of a failure is important before deciding whether repair, adjustment, refurbishment or replacement is required.

Our industrial valve troubleshooting activities address common operational problems, including:

• Internal Valve Leakage: Leakage across the closed valve due to damaged seating surfaces, worn components or foreign particles.
• External Leakage: Leakage from body joints, bonnet connections, packing areas or other sealing arrangements.
• Difficult Valve Operation: Increased operating effort caused by deposits, corrosion, damaged threads or mechanical problems.
• Sticking and Jamming: Restricted movement due to contamination, component wear or improper alignment.
• High Operating Torque: Excessive torque requirements caused by friction, internal damage or actuator-related issues.
• Control Valve Instability: Unstable operation, poor response or irregular flow regulation.
• Actuator and MOV Problems: Electrical, pneumatic or mechanical faults affecting valve movement.
• Vibration and Abnormal Noise: Possible issues associated with flow conditions, cavitation, improper operation or mechanical looseness.
• Seat, Stem and Seal Damage: Deterioration of internal components that may result in leakage or operating problems.
• Safety Valve Set Pressure Issues: Problems relating to opening pressure, reseating performance or the condition of internal components.

Our approach focuses on identifying the probable cause of the problem and recommending a technically suitable repair or maintenance solution.

On-Site Industrial Valve Repair & Maintenance Services

Certain valve maintenance requirements can be addressed at the installation site, particularly when removing equipment from the pipeline is difficult or when plant shutdown schedules require timely attention.

Unitek provides on-site industrial valve repair and maintenance support, subject to site conditions, equipment accessibility, technical feasibility and the agreed scope of work.
