PERFORMANCE
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.
• Auxiliary switch
The actuator contains an auxiliary micro-switch
to operate other devices. The 24 V actuators use
a sealed reed switch, patent pending, which has
been produced specifi cally for use with relays,
boiler contacts (TT) and DDC systems. It requires
no minimum current load. 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 is tripped when the unit is put into
manual open position. This helps during start up to
check if the wiring is correct without fi ring the valve
electrically with the thermostat.
• Easy push button
A simple push of the button makes it easy to remove
it from the body of the valve for maintenance or replacement operations.
• Operation
The actuator is fi tted with a special mechanism for gradual movement of the
valve paddle which provides smooth and quiet constant operation.
