• Perfect match between the actuator and ESBE valves Series VLG100
  • Different control signal available
  • Easy assembly thanks to the threaded ring nut
  • Stroke indicator on actuator

The ESBE Series ALG400 is a thermo-electrical actuator suitable for fan coil valves such as ESBE Series VLG100 in both heating and cooling applications. The actuator has a force of 140N and an operating stroke of 2.5 mm. The actuator –valve assembly is easily made thanks to the threaded ring nut.

The actuator is available in 24V AC/DC or 230V AC versions with 2-point or in 24V AC version with proportional control signal.
