Standards & Pressure Classes
A procurement-friendly overview. Always confirm application requirements with your internal engineering standards and supplier documentation.
Pressure class context
- Pressure class is not a single “PSI” number — it depends on temperature and material.
- Common classes: 150, 300, 600, 900, 1500, 2500.
- Capture pressure class early to avoid quote churn.
Spec-first intake
- Valve type + size + class + material + end connection
- Media + temperature + actuation (if known)
- Quantity + delivery + timeline
Quick checklist before requesting quotes
| Field | Why it matters |
|---|---|
| Valve type | Determines design family and selection constraints. |
| Size | Impacts pressure drop, cost, availability, and lead time. |
| Pressure class | Drives body rating; ties to temperature/material. |
| Material | Compatibility, corrosion resistance, and compliance. |
| End connection | Installation fit (flanged, threaded, weld, etc.). |
