Product information "Belimo CQ230A Rotary Actuator for Zone Valves 1Nm (100–240V)"
The Belimo CQ230A is a compact rotary actuator intended for zone valves in HVAC systems. It provides on/off (2-point) control with AC 230 V supply and 1 Nm torque, making it suitable for small valve actuation duties in fan coil units, small AHU branches, and general zoning circuits.
This actuator is typically used where reliable open/close positioning is required for temperature control, isolation, or zoning control under a thermostat, controller, or BMS output.
Applications
- Zone control of fan coil units (FCU) and small HVAC branches
- On/off isolation of chilled water / hot water circuits (as per valve design)
- Small air-handling / ventilation zoning circuits
- Building automation 2-point valve control from controller/thermostat
