Belimo CQKB24-SR-LL Actuator R-22 provided the original unit utilizesThe 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
