24V Normally Opened Actuator for Straight Through Valve Bodies with micro-switch 18" wire
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, patent pending, which has been produced specifically for use with relays, boiler contacts (TT) and DDC systems. It requires no minimum current load. The 120 V - 277 V actuators, and actuator model number Z111000 HCS 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.
