Caleffi Z-one 2-Way Motorized Zone Valve

The Z-one™ valve is a truly universal zone valve that can be used in a wide range of commercial and residential applications; from fan coils to baseboard, radiant to high rise, the Z-one™ is the professional’s valve of choice.

Two-way zone valve. Spring return.  Normally closed actuator: Z111000.  Auxiliary micro-switch.  Max. body pressure: 300 psi.  Temperature range: 32o—240°F.  Suitable fluids: water, 50% max. glycol, 15 psi max steam.  Power supply: 24 V AC.  Power consumption: 5 W, 7 VA.  Rating of auxiliary micro-switch contacts: 0.0 A min, 0.4 A max 24 V (24 V only).  18" wire lead connection.  UL873, cULus Listed & CE.  UL 1995 sec. 18 air plenums and ducts.  US Patent 7,048,251.

 

The Z-one™ valve is a truly universal zone valve that can be used in a wide range of commercial and residential applications; from fan coils to baseboard, radiant to high rise, the Z-one™ is the professional’s valve of choice.  The Z-one™can be used in both chilled or hot water and low pressure steam applications.  With Delta P close off pressures of up to 75 PSI, the Z-one™outperforms all other zone valves.  The Z-one™is available in sizes from 1/2” to 1-1/4” sweat or NPT connections on valve body, with removable actuator available in 24 to 277 voltages.  Some models of Z-one™actuators contain an auxiliary micro-switch to operate other devices.  The 24 V actuators use a sealed reed switch, which has been produced specifi cally for use with relays, boiler contacts (TT) and DDC systems.  It requires no minimum current load.  The 120 V - 277 V actuators for applications requiring greater than 400 mA, use a conventional micro-switch with silver contacts.  The auxiliary switch is activated when the valve is 60% open or when the actuator is manually opened.

 

The valve can be opened manually by moving the lever for opening it.  When the power is restored the manual control is automatically overridden.  The auxiliary switch in 24 V actuators is tripped when the unit is put into manual open position.  This helps during start up to check if the wiring is correct without firing the valve electrically with the thermostat.  A simple push of the button makes it easy to remove it from the body of the valve for maintenance or replacement operations.  Warning: the actuator can only be used with valve bodies Z2-Z3 series.

 

The actuator is fitted with 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.
