Belimo NV24A-SR-TPC - linear actuator for globe valves

Belimo NV24A-SR-TPC actuator

Modulating actuator for 2-way and 3-way globe valves, designed for stationary heating, ventilation and air conditioning installations. The Y control signal determines the actuator position, while the U feedback voltage is used for electrical position indication.
