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 professionals 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.
Just what I needed to fix the problem (using SR relay) so rather than added more relays just wired the 120v valve body before the pump and used the switch contacts on the valve to power the pump!
