This is the medium-size Rack and Pinion series for torques up to 550.000 Nm. Its design is very flexible, there can be many possible configurations thanks to the modular components and to the design specifically studied to satisfy different dimensional and torque needs.

The interface is developed and optimized to allow the interchange of cylinders and spring packs of the corresponding scotch yoke actuators. By doing so, productivity is optimized and it is possible to reduce costs and delivery time.

The pneumatic version employs tandem and triple cylinders up to a diameter of 935 mm in order to ensure a great dimensional versatility and a wide range of pressure to be used.

  • Extremely compact body with rigid design
  • Rack completely supported  to absorb lateral forces
  • In line external travel stop 90° ±4° to eliminate asymmetrical loads
  • Easily visible local position indicator with Namur interface
  • Std. temperatures (-30° +100°); low (-60°) and high (+200°) on request
  • Totally enclosed IP 66 construction; IP 67 and IP 68 on request
  • Multiple spring design, increased reliability and std. configurations
  • Suitable for high frequency and high speed operation (< 0.2 s)
  • modulation and ON/OFF design to operate in all conditions
  • Compliant to PED 97/23/EC. and ATEX
  • Hydraulic/PneumaticDouble/single acting
  • Manual handwheel override for for double acting and single acting
  • Hydraulic override for both pneumatic & hydraulic execution
  • Manual override with partial stroke test option
  • Fast acting with pneumatic dumper (less then 0.2 seconds)
  • Hydraulic speed regulator for pneumatic actuator
  • Closed loop circuit to avoid internal contamination
