230Vac On/Off Electrothermal Actuator




The SEI Electrothermal Actuators are for use with the VFX range of Fan Coil valves and are used in heating, cooling and air conditioning systems.

When the actuators are not energised the valves are normally closed and two action types are available: On/Off and modulating 0-10Vdc.

Assembly is easy using the metal rings, tools are necessary.

The actuator is fitted with valve position indication.
