How energy efficiency is improved
Torque-dependent cut-off facility for efficient usage of energy
- For operating 2- and 3-way ball valves VKR, VKRA, BKR, BKRA, VKAI, VKAA, BKLI, BKTI, BKTA and 6-way ball valve B2KL
- For controllers with a switching output (2-point control)
- Returns to the starting position in the event of a power failure or the activation of a safety device
- Electronic torque-dependent cut-off
- Direction of rotation can be selected during fitting
