Operating challenges
- Pressure-temperature capability
- Thermal cycling and stem-sealing performance
- Erosion and cavitation review
- Actuation and fail-position definition
- Plant quality and release-document requirements
Operating context
Translate process conditions into valve requirements
Steam, feedwater, condensate and plant-utility applications require careful review of pressure-temperature conditions, cycling, erosion, actuation, maintainability and plant-specific quality documentation.
All constructions, pressure-temperature limits, certifications and inspection requirements must be confirmed against the specific product and purchase specification.
Relevant valve families
- Gate valves
- Globe valves
- Check valves
- Control valves
Materials & standards review
- Carbon, low-alloy and stainless steels
- Hardfacing or trim upgrades when specified
- Applicable ASME and product standards
- Project weld, heat-treatment and NDT requirements
- Nuclear qualification only within an explicitly agreed scope
