SUT valve actuator with safety function

AVN 224S

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 re-initialisation

  • 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
