SAUTER AVF 234S: SUT valve actuator with spring return

AVF 234S: SUT valve actuator with spring return

How energy efficiency is improved

Automatic adaptation to valve, precision activation and high energy efficiency with minimal operating

noise

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 output (0...10 V, 4...20 mA)

• Spring return moves to end position in the event of a power failure/interruption or when a limit con

troller 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 (pa

tented 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 adaptors enable the unit to be fitted onto non-SAUTER valves

• Power supply 230 V with module or direct connection for 24 V~ or 24 V=; 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 al

loy 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
