Understand the condition before deciding the intervention.
A valve fault can involve the valve body, actuator, positioner, control signal or supporting components. Kroft reviews the equipment information and reported symptoms to define an appropriate inspection and testing scope.
Our agreed scope includes valve diagnostics, stroke and functional checks, condition surveys and maintenance recommendations. Findings connect directly to calibration, repair coordination or replacement equipment, rather than treating testing and procurement as separate requirements.
Assessment and checks
- Valve identification and equipment review
- Functional and stroke testing
- Actuator and positioner operating checks
- Shutdown and turnaround valve surveys
Records and follow-up
- Valve tagging and asset register support
- Condition findings and maintenance priorities
- Repair, calibration or replacement recommendations
- Post-maintenance verification and reporting
Test methods, isolation requirements and acceptance criteria are agreed against the equipment, operating conditions and client procedures.
Service questions
What information should I send for a valve diagnostic enquiry?
Include the valve tag, manufacturer, model, size and pressure class, actuator and positioner details, fault symptoms and any available photographs or maintenance records.
Can diagnostics be included in a shutdown scope?
Kroft supports shutdown and turnaround valve surveys. Share the valve list, site, planned access window and required checks so the scope and execution arrangements can be reviewed.
What happens after the assessment?
The findings help define the next step: calibration, maintenance, repair or overhaul coordination, or replacement supply. Verification and documentation are agreed as part of the work scope.
