CUSTOMER CHALLENGE

The customer required valves for use in safety relevant applications in Nuclear Power Plants (NPP) e.g.  annular gap evacuation and to replace old valves.

NORGREN SOLUTION

The solution incorporated a double seat design for extra safety and higher flow performance, and was fully certified for use in German NPP based on tests for function, earthquake-resistance (KSD7021/50, QC 3).

Technical features:
  • Fluid: Air (possibly water)
  • Sizes: DN 15 and DN 50 actually in production. DN 25, 32 and 40 could follow according to demand
  • Pressure range: 0 - 10 bar
  • Temperature range: 0 - 100°C
  • Ambient Temp.: 0 - 50°C
  • Switching function: NC or NO available
