Advantages

Reduce Construction & Life-cycle Costs

  • Body is integral part of platform for lifetime.
  • Cartridge can be replaced, in-line, within minutes.
  • Valve seat is part of removable cartridge.
  • Thirteen different cartridges (interchangeable) within each valve body size.
  • Reduction in spares/inventory.. not necessary to inventory valve body's...
  • End connections-butt weld/socket weld/screwed.
  • Cartridge valves = weight reduction.
  • Cartridge valves = reduced space envelope savings
  • Installed Base = 75,344 cartridge valves
