For higher torques, robust design, manual override (VS)
VR-Serie: For smaller torques (up to 75 Nm), compact design, ideal for butterfly valves and ball valves of medium size.
VS-Serie: For higher torques (up to 300 Nm), additional manual emergency override for safety, suitable for large valves and demanding applications.
The series follows the torque: VR up to 75 Nm, VS from 100 to 300 Nm. Fail-safe is standard on the VS series and must be checked for the VR series – above that the VT Plus takes over.
