Valve actuator HyRAV

The HyRAV rotary actuators form a complete series of dual-action or spring-return rotaty units which work according to the helical gear principle.

The compact and concentric fitting on the valve has proven to be effective in practice and the unit is both space-saving and reliable. This series can be deployed in the most difficult conditions, from heavy vibrations to adverse ambient conditions, and offer a powerful and safe solution for valve control.

Due to the spacious, hollow shaft design and customisable flanges, the series can be adapted to each valve type.

Product advantage

  • small dimensions
  • smallest footprint to torque ratio
  • durable against vibrations
  • easy installation to each valve
  • robust against extreme environmental conditions




  • 12 drive sizes with torques up to 250.000 Nm at 210 bar
  • compact and slim style
  • concentric design protects the valve and the spindle
  • ISO5211 or ANSI flange
  • no lubrication required, because all moving parts of the actuator are permanent in the oil bath
  • ATEX and SIL

additional features:

  • extremely trip: 90° in 0,2 sec
  • optimum cushioning protects the valve and the actuator
  • operating pressure up to 350 bar on request
