Valves for High-Pressure Steam Service
Steam is the most common industrial utility fluid. High-pressure steam (above 50 bar) requires ASME Class 600+ valves with hardened trim to resist erosion. Drain and condensate traps are critical to prevent water hammer.
Pressure Range
1–300 bar
Temperature
100–650°C
Industries
Power generation, Petrochemical, Refinery
What valves are used for High-Pressure Steam service?
Globe valve (OS&Y, rising stem) are recommended for High-Pressure Steam service: Standard for HP steam throttling and control.
Key Properties - High-Pressure Steam
- Erosive at high velocity - hardened trim required
- Thermal shock from cold water contact causes cracking
- High-temp steam oxidises carbon steel surfaces
- ASME B31.1 (Power Piping) governs boiler steam systems
- Water hammer destroys valve internals rapidly
Vajra Industrial Solutions manufactures and supplies valves for High-Pressure Steam service — including globe valve (os&y, rising stem) — in corrosion-appropriate materials selected for the operating conditions described here, with full material and test documentation.

Material Compatibility - High-Pressure Steam
Ratings are indicative. Actual compatibility depends on concentration, temperature, velocity, and presence of contaminants. Always consult corrosion tables or a materials engineer.
| Material | Rating | Notes |
|---|---|---|
| Carbon Steel WCB / A105 | Good | Up to ~425°C. Standard for steam to ASME Class 600. |
| Chrome-Moly (1¼Cr-½Mo, 2¼Cr-1Mo) | Excellent | For high-temperature steam above 425°C. ASTM A217 WC6/WC9. |
| SS 316H (high-carbon) | Good | Austenitic SS for steam above 540°C - superior creep resistance. |
| P91 (9Cr-1Mo-V) | Excellent | Ultra-high temperature steam above 560°C - power plant main steam. |
| PTFE seats | Poor | Not recommended above 200°C. Use metal-seated valves for HP steam. |
