Valve actuator

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






  • Activation of 2-way and 3-way valves of the VUN/BUN, VUD/BUD and VUE/BUE series
  • For controllers with a switching (2- and 3-point) or continuous (0…10 V) output
  • Stepping motor with SAUTER Universal Technology (SUT) electronic control unit and electronic, force-dependent cut-off
  • Automatic recognition of applied control signal (continuous or switched)
  • Coding switches for selecting characteristic and running time
  • Type of characteristic (linear/equal-percentage) can be set on the actuator
  • Automatic adaptation to valve stroke
  • Maintenance-free gearbox
  • Gear unit can be disengaged in order to position the valve by hand (hexagon key provided)
  • Connection with valve spindle performed automatically after control voltage is applied
  • Brass cap nut for fitting the valve
  • Fitting vertically upright to horizontal, not suspended
