Automatic adaptation to valve, optimal operator convenience, precision activation and high energy efficiency with minimal operating noise
Features
In ventilation air conditioning units for actuating 2- and 3-way valves of type series AVM 321S: VUD, VUE, VUN, BUD, BUE, BUN and AVM 322S: V6R, VQD, VQE, VUG, VUP, VUS, B6R, BQD, BQE, BUG, BUS
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 with 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
Mounting column made of aluminium
Fixing bracket made of cast light alloy for valve fitting with 20 mm stroke and made of plastic for valve fitting with 8 mm stroke
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 vertically upright to horizontal, not suspended
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.
