Function
Z-one valves are used to automatically shut-off the flow or redirect hot and chilled water in hydronic
heating and air conditioning systems, and is UL listed for plenum installations.
The motorized two position, on/off, spring return Z1 series actuator has an end mounted push button
for quick installation to valve body. The actuator is equipped with or without auxiliary switch and
configured Normally Closed or Normally Opened with wire or terminal connections.
The zero leakage high temperature zone valve body Z2 series is 2-way straight through and the valve
body Z3 series is 3-way diverting. The Z1 series actuator is easily attached by a push button lock and
without tools.
The high temperature and high close-off performance characteristics of these zone valves, combined
with the compact size, makes them suitable to fit inside baseboard or directly in fan coils units.

Operating principle
The Z-one actuator has a synchronous motor that winds the return
spring and moves the valve paddle to the desired position. When
power is removed the actuator spring returns the valve paddle. The
Zone actuator is equipped with or without auxiliary switch.

• Auxiliary switch
The actuator contains an auxiliary
microswitch 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
microswitch 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 firing 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.
Warning: the actuator can only be used with valve bodies Z2-Z3 series.
• Operation
The actuator is fitted with a special mechanism for gradual movement
of the valve paddle which provides smooth and quiet constant
operation. Power-on full stroke run time is 60 seconds with 6 second
power-off return time eliminating the effects of water hammer.
Installation
- The valve can be fitted either vertically or horizontally, with the
actuator in any position, except upside down.
-
If it is installed inside a encloser it is important to ensure that there
is adequate ventilation inside the encloser itself.
-
The three-way valve cannot be transformed into a two-way valve
and vice versa.
- When zone valves are installed, the direction of flow must be
observed as shown in the diagrams below.
- Two-way zone valves can be installed on both the flow and return
sides; the direction of flow indicated by the arrow on the body of
the valve must be observed.
- Three way zone valve can be fitted with NC actuator only (rotate
180° the valve body for NO application).
