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 • Actuation 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 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 adapters 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 |
