Retrofit actuator

How energy efficiency is improved

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


Funktioner

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

  • For controllers with constant output (0…10 V / 4…20 mA) or switching output (2-point or 3-point control)

  • BLDC motor (brushless DC) with SUT (SAUTER Universal Technology) electronic control unit of the third generation and electronic load-dependent cut-off

  • Automatic detection of applied control signal (continuous or switching), operating indicator using bi-colour LED

  • Automatic adaptation to the stroke of the valve, between 8 and 20 mm

  • Low operating noise

  • With the built-in absolute distance measurement system, the position is always maintained in the case of power failure

  • The direction of operation, characteristic (linear/equal percentage), positioning time and control signal (voltage/current) can be adjusted via coding switches

  • Integrated forced operation can be set via coding switches (with selectable direction of operation)

  • Easy re-initialisation using a coding switch

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

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

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

  • Electrical parallel operation of five actuators

  • Parameterisation option via the BUS interface

  • 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 glands made of plastic M20 × 1.5

  • Fitting position vertically upright to horizontal, not suspended

  • Nominal actuating power 1000 N

SAUTER Head Office was the target of a cyber security incident on November 20, 2024. SAUTER’s IT department immediately activated, well defined, internal emergency plans. All IT systems were completely isolated and shut down to successfully prevent the attack from spreading. External cybersecurity experts and data forensics specialists then began to check all systems and restore them securely. This process is unfortunately time-consuming, but absolutely necessary to ensure that the cyber-attack does not continue at a later date.


The SAUTER websites have been affected by the emergency operation and are available again with immediate effect.


There are currently no concrete indications that our customers' infrastructures have been compromised in any way by SAUTER devices. It appears to be an opportunistic incident with no clearly recognisable long-term goals or systematic attacks. The situation does not currently suggest that there is a targeted, sustained threat to the affected systems.
