SUT valve actuator with safety function

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 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 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
