Power-free, the Ballorex Dynamic AE01 modulating thermo-electric actuator opens or closes DN15 - 25 valves using a 0 - 10 V DC signal provided by a room thermostat or building management system (BMS). On application of the control voltage, the actuator opens a valve proportionally to the detected actuator travel.

The Danfoss AME435 modulating actuator is designed for use with two and three-way valve types VRB, VRG, VF and VL up to a diameter of DN80 or with AHQM DN40 - 100. Automatically adapting its stroke to the valve end position, this self-stroking actuator reduces commissioning time for cost-effective, fast set-up. AME438's advanced design includes a load-related switch-off, keeping actuators and valves safe from overload while a spring-up safety feature retracks the actuating stem to end position in case of power failure or switch off without further manual stem positioning being disabled.
