Retrofit actuator

How energy efficiency is improved

Automatic adaptation to valve, optimal operator convenience, precision activation and high energy efficiency with minimal operating noise


  • In ventilation and air conditioning units For actuation of 2- and 3-way valves

  • For controllers with a switching output (2-point or 3-point control)

  • Synchronous motor with electronic control unit and load-dependent cut-off

  • Direction of operation and positioning time can be set using coding switches

  • Crank handle for external manual adjustment with motor cut-off

  • Low operating noise

  • Simple assembly onto valve; spindle is automatically connected after nominal voltage is applied

  • Numerous adapters enable the unit to be fitted onto non-SAUTER valves

  • Electrical parallel operation of five actuators

  • Three-piece housing made of flame-retardant yellow/black plastic and seals with type of protection IP54

  • Maintenance-free gearbox made of plastic; threaded spindle and gearbox base-plates made of steel

  • Patented actuator-valve coupling

  • Electrical connections (max. 1.5 mm²) with screw terminals

  • Two break-out cable inlets for metric cable gland made of plastic M20 × 1.5

  • Fitting position vertically upright to horizontal, not suspended
