Welcome to Chuanglan Valve’s valve technical resources page. Here you can find dimension tables, pressure-temperature ratings, material specs and ordering codes for all our stainless steel valves.
1. Ordering Code System
When you send an inquiry, you don’t need to memorize our figure numbering system. Just provide a full description of the valve you need (type, size, pressure, end connection, material), and our sales team will compile it into the corresponding figure number.
2. Pressure-Temperature Ratings (Carbon Steel per ASME B16.34)
Working pressure ratings for carbon steel body valves. Stainless steel ratings are available on request in our catalog PDF.
| Pressure Class | Working Pressure @ 100°F (PSI) | Working Pressure @ 100°F (bar) |
|---|---|---|
| Class 150 | 285 PSI | 19.7 bar |
| Class 300 | 740 PSI | 51.0 bar |
| Class 600 | 1480 PSI | 102.0 bar |
| Class 900 | 2220 PSI | 153.1 bar |
| Class 1500 | 3705 PSI | 255.5 bar |
| Class 2500 | 6170 PSI | 425.4 bar |
Note: Actual de-rating at elevated temperatures depends on body material. Full temperature de-rating charts are available in our full catalog PDF.
