The COMPACT actuator is a quarter-turn rack & pinion pneumatic actuator that doubles the torque of standard pneumatic actuators. The superior performance is achieved by Habonim’s patented four piston design, which generates torque around a centrally located piston. This translates into double the power for the same size actuator or half the size for the same amount.

Unique design
  • Pistons with balanced centralized forces of pistons on pinion
  1. Double the torque of same sized regular actuator
  2. Less wear & tear on moving parts
  3. Longer sealing with no maintenance
  4. Shorter and smaller pistons with shorter travel distance
  5. Compact square shape with minimized footprint
  • Shorter open/close time – allows superior ESD functionality
  1. Smaller air consumption
  2. Lightweight
  • Four short spring sets – up to three nested springs against each cylinder
  1. Selection of springs mix to provide flexible spring torques for the available air supply pressure
  2. Spring cartridge option provides higher torque with better characteristics for opening or closing
  3. Redundancy in case of spring failure – the other three springs will maintain rotation
Meticulous material, treatment and coating selection
  • Selection of body and moving parts materials to best support long lasting performance
    in harsh, controlled and clean environments
  • Structure and surface treatments of part and special coatings to ensure long lasting safe
    operation in harsh environments
  • Selection of sealing and greasing material to accommodate to low and high temperatures
    and application requirements
Standard interfaces:
  • Designed and tested in accordance with EN 15714-3 – Industrial valves – Actuators – Part 3:
    Pneumatic part-turn actuators for industrial valves – Basic requirements
  • ISO 5211 Industrial valves – part-turn actuator attachments
  • VDI/VDE 3845 (NAMUR) Industrial process control – pneumatic control valves – interfaces of valves and auxiliary equipment

Testing & acceptance criteria: 100% internal & external bubble leak tested.
