24V Normally Closed 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.

caleffi zone valve
By J & J antique gas pumps
from littleton colorado
the new valve with end switch does not break like the old ones . the old needed low constant voltage and any surge would break the end switch. the later ones came with a capacitor witch most people did not know what it was for , ( to control voltage spikes). so most broke with spikes anyway. the new valve has it built in and makes it one of the most long lasting valves , dependable ******
