difference between high temperature ball valve and ordinary ball valve
| Terms | high temperature ball valve | ordinary ball valve |
|---|---|---|
| Temperature range | -196℃~600℃(hard seal) | -20℃~150℃(soft seal) |
| Sealing form | Metal/graphite composite seal, resistant to high pressure and high temperature | Conventional rubber/PTFE seals are prone to high temperature aging. |
| Structural design | Spring preloaded valve seat, pressure relief hole, anti-creep material | No high temperature adaptability design, standard sealing structure |
High Temperature Ball Valves
Selection and maintenance points
Selection principle:
Medium characteristics: Corrosive media should preferably choose 316L stainless steel valve body + hard seal combination.
Working parameters: Ultra-high temperature (≥500℃) scenes require chromium-molybdenum steel valve body + tungsten carbide seal structure.
Maintenance requirements:
Regular inspection: Sealing surface wear, valve stem lubrication status (once every 6 months).
Replacement cycle: Graphite seals are recommended to be replaced every 2 years, and metal seals can be extended to 5 years.
