Description

Industrial Valve Modification Services

Industrial Valve Modification Services help adapt existing industrial valves to changing process, operational, automation and maintenance requirements. Valve modification can provide a practical way to upgrade existing equipment without replacing the complete valve assembly.

Unitek Services provides industrial valve modification and retrofit support based on the valve type, application, operating conditions and customer’s requirements. Modifications may involve valve operators, actuators, trims, accessories, connections or other components, subject to technical evaluation.

Why Modify an Existing Industrial Valve?

Industrial operating requirements can change over time. A valve that was suitable for an earlier application may require modification because of changes in process conditions, automation requirements or operating methods.

Valve modification can help:

• Adapt valves to updated process requirements
• Improve valve operation
• Support automation requirements
• Upgrade manual valve operation
• Accommodate new actuators or operators
• Replace unsuitable or worn components
• Improve maintainability
• Extend the useful service life of existing equipment
• Reduce the need for complete valve replacement where modification is practical

Valve Actuator & Operator Modifications

Where suitable, existing manually operated valves can be evaluated for actuator or operator upgrades.

Our support may include:

• Actuator selection support
• Actuator installation
• Gearbox servicing or replacement
• Manual-to-actuated conversion
• Mounting arrangement modification
• Coupling and interface modifications
• Valve operation checks
• Functional testing

The suitability of an actuator modification depends on factors such as valve type, size, operating torque, pressure conditions, available space and application requirements.

Valve Trim Modifications

Valve trim components directly affect valve operation and process performance. Where required, modifications may include changes to selected internal components, seats or other trim-related components.

The modification scope is determined after reviewing the valve design, application and operating requirements.

Valve Automation Support

Existing industrial valves may sometimes be upgraded to support automated operation.

Depending on the application, automation-related modifications may include:

• Actuator installation
• Positioner support
• Solenoid valve installation
• Limit switch installation
• Feedback arrangements
• Control accessories
• Operator upgrades

All modifications should be evaluated for compatibility with the existing valve and the intended operating conditions.

Our Valve Modification Process

1. Valve Assessment

The existing valve is reviewed based on its type, size, design, condition and application.

2. Requirement Review

The required modification, operating objective and customer requirements are evaluated.

3. Modification Planning

A suitable modification scope is identified based on technical feasibility and valve configuration.

4. Component Selection

Required actuators, operators, accessories, seals, trims or other components are identified.

5. Modification Work

The agreed modifications are carried out using suitable methods and components.

6. Assembly

The modified valve is assembled and adjusted as required.

7. Inspection & Testing

The completed valve is inspected and tested according to the agreed requirements.

8. Final Delivery

The modified valve is prepared for installation or return to service.

Industrial Valve Retrofit Services

Our industrial valve retrofit services can support customers looking to upgrade existing valves rather than replace complete assemblies.

Retrofit requirements may include:

• Valve automation
• Actuator upgrades
• Operator conversion
• Control accessory installation
• Component upgrades
• Application-specific modifications

Each retrofit requirement is evaluated individually because valve designs and operating conditions vary.
