Belimo NVKC24A-MP-TPC - linear actuator for globe valves

Belimo NVKC24A-MP-TPC actuator

Communicating actuator for 2- and 3-way globe valves. If the power supply fails, energy stored in the capacitors moves the valve to the configured safety position, taking into account the power-fail delay (PF).
