Z1
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 ½” to 1¼” sweat or NPT connections on valve body, with
removable actuator available in 24 to 120 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 specically for use with relays, boiler contacts (TT) and
DDC systems. It requires no minimum current load. The 120 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.
• Manual opening (Normally closed actuator
only) 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 ring the valve electrically
with the thermostat.

Construction details
• Auxiliary micro-switch
The actuator contains an auxiliary microswitch to
operate other devices. The 24 V actuators use
a sealed reed switch, which has been produced
specically for use with relays, boiler contacts (TT)
and DDC systems. It requires no minimum current
load. The 120 V actuators use a conventional micro-
switch with silver contacts. The auxiliary micro-switch
is activated when the valve is 60% open or when the
actuator is manually opened.
