Change-Over Valves

Change-Over Valves

Change-over valves for increased plant availability and bursting discs in type-tested combination with safety valves.

ADVANTAGES

  • Low pressure loss due to streamlined construction
  • Compact construction for space saving installation
  • Bursting disc (KUB) in combination with safety valves:
  • Tightness until opening
  • Component-tested safety valve and bursting disc combination: conformity to the 3% criteria–bursting disc does not have to be factored-in during layout.
