Caleffi Z-one Normally Closed Actuator for Motorized Zone Valves
24VAC, PN - Z111000
Made In Italy
The Z-one actuator has a synchronous motor that winds the return spring and moves the valve paddle to the desired position. When power is removed the actuator spring returns the valve paddle. 24V actuators use a sealed reed switch for end switch, requiring no minimum current load.
Fits on Z2 and Z3 Series valve bodies with the push of a button.
A gear ratio of 21:1 in the actuator increases torque for high close-off pressure and increases closing time to reduce water hammer.
