 Positioners

  • Positioners use  feedback information to ensure that actuator is in the correct position.
  • Can assist in overcoming friction and greater actuating pressures are available.
  • Works on principle of "Pressure Balance".
  • Rugged construction.
  • Amplify pressure to the actuator.
  • Allows characterisation either mechanically (by feedback cam) or electronically (smart positioner).
  • Negates variable process reaction pressure effect on position.
  • Allows split ranging.
 

Product Benefits Product Specifications Applications Technical Documentation
  • Works on the force-balance principle
  • Split range of operation is possible
  • Short response time: lesser moving parts
  • Vibration proof: Valves are constantly exposed to vibrations. Forbes Marshall Positioners are robust and operate even under most difficult conditions
