The Z-one valve is a truly universal zone valve that can be used in awide range of commercial and residential applications; from fan coils tobaseboard, radiant to high rise, the Z-one is the professionals valveof choice. The Z-one can be used in both chilled or hot water and lowpressure steam applications. With Delta P close off pressures of up to 75PSI, the Z-one outperforms all other zone valves. The Z-one is availablein sizes from 1/2" to 1-1/4" sweat or NPT connections on valve body, withremovable actuator available in 24 to 277 voltages.Some models of Z-one actuators contain an auxiliary micro-switch tooperate other devices. The 24 V actuators use a sealed reed switch, patentpending, which has been produced specifically for use with relays, boilercontacts (TT) and DDC systems. It requires no minimum current load. The120 V - 277 V actuators, and actuator model number Z111000 HCS forapplications requiring greater than 400 mA, use a conventional micro-switchwith silver contacts. The auxiliary switch is activated when the valve is 60%open or when the actuator is manually opened.
