Valve technology

Baelz thermal oil valves have a broad range of industrial applications

Our thermal oil valves are suitable for special applications in temperature ranges from -10°C to 400°C. The nominal diameters range from DN 15 to 300.

Advantages at a glance
  • Easy replacement of defective components
  • Very low leakage
  • High variability/flexibility
  • Low-maintenance
