Belimo GRC24G-SZ-T-5 - Rotary actuator for valves

Belimo GRC24G-SZ-T-5 – rotary actuator

Actuator designed for rotary valves and dampers in stationary heating, ventilation and air-conditioning systems. The control signal Y determines the actuator position, while the feedback voltage U is used for electrical indication of the valve position.
