Belimo CQK230A-T - rotary actuator for zone valves

Belimo CQK230A-T – actuator for zone valves

CQK230A-T is a rotary actuator with a safety function. If the power supply is interrupted, energy stored in the integrated capacitors moves the valve to the safe position: closed (NC).

Key features and specifications

• Motor torque: 1 Nm.
• Rated voltage: AC 100...240 V; frequency: 50/60 Hz.
• Control: Open/Close.
• Motor running time: 75 s / 90°; safety function running time: 60 s / 90°.
• Power consumption during operation: 2.5 W; in standby position: 0.5 W; power rating for cable sizing: 5 VA.
• Power and control connection: 2.5 mm² terminals (cable ø6.3...6.8 mm, 2-core).
• IEC/EN protection rating: IP40; IEC/EN protection class: II, reinforced insulation.
• Tool-free clip-on mounting and mechanical position indicator.
• Rotation angle adjustment using a clip in 2.5° increments allows the valve's maximum flow to be set.

In the event of a power failure, the actuator takes into account the factory-set power-fail (PF) time of 1 s. The valve can be repositioned manually after the actuator is detached.
