Globe Valves for Hot Oil (Thermal Heat Transfer Fluid) Service
Which globe valves configuration suits Hot Oil (Thermal Heat Transfer Fluid), in which material, to which standard — from real service data, with the pitfalls flagged.
Which globe valves for Hot Oil (Thermal Heat Transfer Fluid)?
Globe Valve (cast steel, metal seated) - Flow control and modulating service on hot oil supply to heat exchangers. Typical service window: 1–15 bar (circulation system pressure), 150–400°C (design temperature drives alloy steel selection above 370°C).

Governing Standards for Hot Oil (Thermal Heat Transfer Fluid) Service
What to Avoid in Hot Oil (Thermal Heat Transfer Fluid) Service
- PTFE-seated ball valves (temperature limit exceeded)
- Cast iron body valves (thermal shock and brittleness risk at high temperature)
- Plastic or elastomer-sealed valves
Service Considerations
- Thermal expansion - hot oil systems experience significant pipe expansion; flexible connections near valves
- Fire risk: hot oil leaked onto surfaces above its autoignition temperature can self-ignite - fire-safe valves required
- Graphite packing mandatory above 200°C - PTFE packing will fail
- Thermal cycling: valve bodies should be specified for the full temperature range including cold start
