Give the manufacturer and complete part number if known, or describe the valve with the specifications available. In MCP, a technical-discovery search can use nominal size, end connection and other supplied details even when the pressure rating is unknown. The web app may have different intake readiness requirements. The result may remain discovery-only and require confirmation before procurement.
Provide the application pressure and temperature rating, materials, service and installation dimensions when known. The search may ask for further information depending on the request and product flow.

- An exact manufacturer and part number can help identify a reference; verify the identified valve.
- Technical discovery can use supplied dimensions and construction even when the reference is unknown. Review missing ratings and application-specific requirements.
NPS and DN are nominal size systems; they are not exact measured bore dimensions.- ASME Class, PN, and CWP/WOG are different rating systems and should not be treated as interchangeable without policy evidence.
- Face-to-face and end-to-end are decisive for fixed-piping replacements.
