Product data sheet AVN 224S: SUT valve actuator with safety function How energy efficiency is improved Automatic adaptation to valve, precision activation and high energy efficiency with minimal operating noise Features • Operation of 2-way or 3-way valves of type series VUG/BUG and VUP as per DIN EN 14597 • For controllers with constant output (0...10 V or 4...20 mA) and switching output (2-point or 3-point control) • Valve actuator with safety function (as per DIN 32730, DIN EN 14597) and pushing force of 1100 N, in normally closed (NC) or normally open (NO) version • 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 recognition 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 valve stroke (min. valve stroke 8 mm, max. valve stroke 49 mm); the measured stroke is stored and is not lost in the event of a power failure • Direction of operation can be selected via screw terminals when making the electrical connection • Push-buttons on outside of housing for manual adjustment with motor cut-off and as trigger for reinitialisation • Numerous adaptors enable the unit to be fitted onto non-SAUTER valves • 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 break-out cable inlets for M20 × 1.5 (2×) and M16 × 1.5 • Fitting vertically upright to horizontal, not suspended Technical data Power supply Power supply 24 V~ Power consumption Running time of motor Actuating power Number of spring returns Positional feedback signal Ambient conditions Admissible ambient temperature Admissible ambient humidity Spring return time equates to stroke of 14...40 mm and does not depend on set running time

Product data sheet End stop (needed for V/BXD, V/BXE DN 15…50, V/B6 DN 15 with kvs ≤ 1 m3/h) Cable screw fitting M16 × 1,5 Cable screw fitting M20 × 1.5 SAUTER Satchwell VZF1727 mounting set Adaptor: Not needed for version AV*2*4SF132-6 Potentiometer 130 Ω: This potentiometer must only be used as a voltage divider. Description of operation After a restart or a start after triggering of the emergency function (terminal 21), a waiting time of up to 45 s elapses until the actuator is available again. Depending on the type of connection (see connection diagram), the actuator can be used as a...

Product data sheet Once the actuator is connected to the valve, the safety screw must be fitted in the locking ring. When the safety screw is fitted, a manual initialisation must be triggered. To do this, the two pushbuttons must be pressed for at least 5 s. The actuator then moves to the lower limit stop of the valve. Then it moves to the upper limit stop. The distance is measured and stored by a travel measurement system. The control signal and the feedback are adapted to this effective stroke. After a power failure or an emergency function, no re-initialisation is carried out. The values...

Product data sheet Direction of operation 2 (mains power supply on internal connection 2b): When the positioning signal is increasing, the actuator spindle moves in. The starting point and control span are fixed. To set partial ranges, a split-range unit is available as an accessory (only for voltage input 3u) – see the split-range unit function – which is intended to be installed in the actuator. After the connection of the power supply and the initialisation, the actuator moves to every valve stroke between 0% and 100%, depending on the control signal. Thanks to the electronics and the...

Product data sheet Auxiliary change-over contacts 0372333 001 Switch rating max. 250 V~, current min. 250 mA at 12 V (or 20 mA at 20 V) Switch rating max. 12...30 V=, current max. 100 mA Switch rating max. 250 V~, current min. 1 mA at 5 V Switch rating max. 0.1...30 V=, current 1...100 mA If it is used one time in the range up to 10 mA or up to 50 V, the gold plating is eliminated. The switch can then only be used for a higher switch rating. Warning • If there is a high media temperature in the valve, the actuator columns and the spindle can attain similarly high temperatures. • Actuators...
