The NR230-04-401 actuator is used for the motorised actuation of three- and four-way mixing valves. The actuators can be controlled by all commercially available control systems with output for floating control.
The flow temperature rises when the actuator turns clockwise until the motor end stop is reached (supply open, bypass closed). The flow temperature decreases when the actuator turns anticlockwise until the opposite end stop is reached (supply closed, bypass open).
The angle of rotation is limited to 90°. When the end stops are reached, the actuator is switched off electrically and is de-energised. If the control system malfunctions, the actuator can be set to manual mode using an additional rotary knob.
For subsequent installation in the Regumat M3 stations DN 25 manufactured from 2015 onwards, the mounting set for actuators, item no. 1350290, is also required.
