Marine Valves by Operating Temperature
In marine engineering, valves are also systematically categorised by working temperature, as this parameter directly governs material selection, seal compatibility and pressure‑retaining design. Drawing on established shipbuilding practice and class rules, five temperature bands are commonly recognised
Overview
Valves by Operating Temperature
| Valve Classification | Temperature Range |
|---|---|
| Cryogenic valves | t < −100°C |
| Low-temperature valves | −100°C ≤ t ≤ −29°C |
| Normal-temperature valves | −29°C < t < 120°C |
| Medium-temperature valves | −120°C ≤ t ≤ 425°C |
| High-temperature valves | t > 425°C |
