Operating challenges
- Seawater material compatibility
- Compact installation envelope
- Manual or remote actuation requirements
- Marine coating and identification
- Classification-society requirements when specified
Operating context
Translate process conditions into valve requirements
Marine service requires compact, maintainable valve configurations with materials, coatings and actuation suited to seawater, ballast, utility and shipboard process systems.
All constructions, pressure-temperature limits, certifications and inspection requirements must be confirmed against the specific product and purchase specification.
Relevant valve families
- Ball valves
- Butterfly valves
- Gate valves
- Check valves
Materials & standards review
- Bronze, stainless and duplex options
- Project coating and fastener requirements
- Shipyard or classification rules supplied with the RFQ
- Flanged, wafer and threaded connections
- Fire-main and ballast-system duty definition
