G122-828 VP Controller – Low cost injection molding

(Closed loop velocity and pressure control)

The Moog G122-828 VP Controller, combined with a Moog servo valve, a position or velocity transducer and a pressure transducer, provides closed loop control of the injection cycle of a plastic injection molding machine.


The functions controlled during the cycle are:

  • Injection speed
  • Injection pressure limiting
  • Hold pressure during setting
  • Back pressure during plasticising
