SUT valve actuator with spring return AVF234SF132 Sauter, AVF234SF132 Sauter, AVF234SF132-5 Sauter, AVF234SF232 Sauter 

Features
• Activation of 2-way and 3-way valves of the VQD/BQD, VQE/BQE, VUG/BUG, VUP, VUS/BUS and
V6R/B6R series
• For controllers with switching (2- and 3-point) and continuous (0...10 V, 4...20 mA) output
• Spring return moves to end position in the event of a power failure/interruption or when a limit
controller is activated
• Stepping motor with SAUTER Universal Technology (SUT) electronic control unit and electronic,
force-dependent cut-off
• Simple assembly with valve; spindle is automatically connected after control voltage is applied
(patented system)
• Automatic detection of applied control signal (constant or switched); indicated by two LEDs
• Coding switches for selecting characteristic and running time
• Type of characteristic (linear/quadratic/equal-percentage) can be set on the actuator
• Automatic adaptation to the stroke of the valve (min. valve stroke 8 mm, max. valve stroke 49 mm).
The measured stroke is saved and is not lost even in the event of a power failure
• Direction of operation can be selected via screw terminals when making the electrical connection
• Crank handle for external manual adjustment with motor cut-off and as trigger for a re-initialisation
• Numerous adapters enable the unit to be fitted onto non-SAUTER valves
• Power supply 230 V with module or direct connection for 24 VAC or 24 VDC; continuous activation
also admissible with 230 V
• Maintenance-free gear unit made of sintered steel; gearbox base-plate made of steel
• Spring pack and mounting column made of stainless steel; mounting bracket made of cast light
alloy for valve fitting
• Electrical connections (max. 2.5 mm²) with screw terminals
• Three pre-scored cable inlets for M20 × 1.5 (2×) and M16 × 1.5
• Fitting vertically upright to horizontal, not suspended
