Rotary actuator for ball valve

Torque-dependent cut-off facility for efficient usage of energy.





  • For operating 2- and 3-way ball valves VKR, VKRA, BKR, BKRA, VKAI, VKAA, BKLI, BKTI, BKTA, (AKM115S) and 6-way ball valve B2KL
  • For controllers with constant output (0…10 V) or switching output (2-/3-point control)
  • Assembly with ball valve without the use of tools
  • Stepping motor with SAUTER Universal Technology (SUT) electronic control unit
  • Electronic force-dependent motor cut-off
  • Automatic recognition of applied control signal (continuous or switched)
  • Coding switch for selection of characteristic and running time (35 s, 60 s, 120 s)
  • Type of characteristic (linear/quadratic/equal-percentage) can be set on the actuator
  • Direction of operation can be selected directly on the cable
  • Maintenance-free gear unit
  • Gear unit can be disengaged in order to position the ball valve manually (using the lever)
  • Bracket and bayonet ring made of glass-fibre-reinforced plastic for fitting onto ball valve
