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

Belimo AVK24A-MP-RE actuator

Communicating RetroFIT+ linear actuator for 2- and 3-way globe valves. It can operate with an analogue control signal or receive digital commands via MP-Bus. If the power supply fails, it moves the valve to the selected fail-safe position using energy stored in the capacitors.
