SUT valve actuator with positioner

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 and VQE/BQE series, as well as VUG/BUG, VUS/BUS, VUP, V6R/B6R and VDL

  • For controllers with constant output (0…10 V or 4…20 mA) or switching output (2-point or 3-point control)

  • 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 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 adapters enable the unit to be fitted onto non-SAUTER valves

  • Power supply 230 V with module or direct connection for 24 VAC / 24 VDC; continuous activation also admissible with 230 V

  • Maintenance-free gear unit made of sintered steel; gearbox base-plate made of steel

  • Mounting column made of stainless steel; mounting bracket made of cast light alloy for fitting the valve

  • 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
