The SAS 61.03/MO electric actuator with remote Modbus communication is suitable for 2- and 3-way lift valves V..G44.., VVG55.., and VVG549 with a lift height of 5.5 mm in heating, air conditioning, and ventilation systems. The valves can be used both as control and shut-off valves.

The actuator is very easy to install and requires no special modifications. It features LED indicators for movement and status on its body. It can optionally be expanded with additional functions and an auxiliary switch. It can also be fitted to older types of valves using the ASK 30 mounting kit. With it, it can control valves X3i.., VVG45.., VXG45.., VXG46.., and VVI51...

Features:

  • Voltage 24 VAC/VDC
  • Positioning force 400 N
  • Positioning time 30 s
  • Modbus RTU
  • Lift 5.5 mm
  • Manual adjustment

Functions:

  • Self-calibration - must be performed during the first commissioning. The actuator moves to the lower end position and stores the measured values.
  • Valve seat detection - depends on the actuator's performance. After calibration, the actuator stores the exact valve lift in memory.
  • Foreign body detection - the actuator can detect the presence of a foreign body in the valve and its blockage. If this occurs, the actuator will make three attempts to release the valve. If unsuccessful, the actuator will activate the LED signal and continue in limited operation.
  • Modbus RTU - not galvanically isolated. It receives the desired valve position (0...100%), transmits the current position (0...100%). It remotely controls the valve Open / Close / Min / Max / Stop. It monitors the desired value and backs up the settings.
