Keystone F89U Pneumatic actuator

  • Compact rack and pinion design utilising the whole piston area to develop output torque.
  • Pistons with integral rack drive reducing the number of dynamic seals, minimising air leakage.
  • Double pistons nullify sideloads on the pinion shaft, minimising bearing wear.
  • Hard anodised aluminium body, with external ESPC finish, protects against corrosive environments including saliferous atmospheres.
  • Keyed female output drive enabling tight fit for any adaptors required for mounting to control
  • Anti-friction piston pads ensuring no metal to metal contact, providing a smooth operation. Ideal for modulating or on/off control applications.
