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

Belimo AVK24A-3-TPC

Linear actuator for 2- and 3-way globe valves. During normal operation, the built-in capacitors are charged; if the power supply is interrupted, the stored energy moves the valve to the selected safety position. This position can be set using the POP knob.
