Caleffi Z-one Normally Closed Actuator for Motorized Zone Valves230VAC, PN- Z114000 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. 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. The actuator uses a special mechanism for gradual movement of the valve paddle which provides smooth and quiet constant operation. Power-on full stroke run time is 60 seconds with 6 second power-off return time eliminating the effects of water hammer. When power is delivered to the actuator, the motor drives a series of gears against a pre-wound torsion spring until it reaches its fully stroked position. When power is dropped to the actuator, the torsion spring back drives the motor and gear train until the unit returns to its normal position. A lost motion mechanism disengages the motor from the gear train at the end of stroke to prevent the impact that would occur in directly coupled gears. This allows the Z-one actuator to have high spring force resulting in higher close-off pressures without compromising motor and gear longevity. The valve can be installed either vertically or horizontally, with the actuator in any position, except upside down.
