The most diverse applications are necessary to manufacture polyethylene terephthalate (PET). Many different kinds of media are involved: nitrogen, steam and condensate, ethylene glycol and water in addition to thermal oil as the heat transfer medium up to 360°C (~8 bar). Additives, catalyst and stabiliser solutions and vacuum applications are also used.

Almost any valve that helps this equipment operate reliably and continuously can be supplied by ARI, e.g.

  • Control valves
  • Stop valves
  • Safety valves
  • Steam traps
  • Manifolds
  • Separators
  • Pressure reducing valves
  • Check valves
  • Strainers

Optimal reliability and availability are vital for you, which is why ARI products are manufactured to the highest possible quality standard.  Each customer's plant is unique and ARI valves are carefully tailored to your specific requirements – no matter whether you’re looking for positioners with HART communication, for instance, filter reducing stations or solenoid valves with a silencer.
