Belimo AVK24A-3-RE - linear actuator for globe valves

Belimo AVK24A-3-RE actuator

RetroFIT+ linear actuator for 2- and 3-way globe valves. The integrated capacitors are charged during operation; if the power supply is interrupted, the stored energy moves the valve to the selected safety position.
