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 VUN/BUN, VUD/BUD and VUE/BUE series
- For controllers with a switching (2- and 3-point) or continuous (0…10 V) output
- Stepping motor with SAUTER Universal Technology (SUT) electronic control unit and electronic, force-dependent cut-off
- Automatic recognition of applied control signal (continuous or switched)
- Coding switches for selecting characteristic and running time
- Type of characteristic (linear/equal-percentage) can be set on the actuator
- Automatic adaptation to valve stroke
- Maintenance-free gearbox
- Gear unit can be disengaged in order to position the valve by hand (hexagon key provided)
- Connection with valve spindle performed automatically after control voltage is applied
- Brass cap nut for fitting the valve
- Fitting vertically upright to horizontal, not suspended
