Belimo CQKB24-SR-LL Actuator R-134A Field-Replaceable Components: The internal timing

Field-Replaceable Components: The internal timing mechanism and terminal board can be interchanged in the field

allowing for accurate air temperature sensing within terminal units while the main control body remains accessible for adjustment

High Thermal Dissipation: The rugged steel housing is designed for superior heat rejection in tight mechanical compartments

Is this 5-ton TXV compatible with older R-22 systems

which effectively mitigates the impact of condensing pressure fluctuations on the opening degree

Belimo CQKB24-SR-LL Actuator R-134A Field-Replaceable Components: The internal timingThe Belimo CQKB24 SR LL is a specialized electronic fail safe actuator designed for ZoneTight zone valves, delivering precise control in hydronic systems. Operating on a 24V AC DC power supply, it utilizes a proportional 2 10VDC or 4 20mA control signal to provide modulating performance. This model features a normally open (N O) fail safe position, ensuring the valve returns to its de energized state during power loss using low maintenance capacitor
