How energy efficiency is improved
Electric cut-off to save energy
- Activation of through and 3-way valves of the VUN/BUN, VUD/BUD and VUE/BUE series, DN 15 to DN 50. For controllers with a switching output (3-point control)
- Spring return facility moves the unit to the end position in the event of a power failure or when a limit controller is activated
- Stepping motor with electronic control unit and electronic, force-dependent cut-off
- Maintenance-free gear unit
- LED display/indicators
- Coding switch for changing the running time
- Electrical connections (max. 1.5 mm²) with screw terminals
- Cable inlet M20 × 1.5
- Fitting vertically upright to horizontal, not suspended
