Z-one
™
Z1, Z2, Z3 Series
Function
The Z-one, a two-position spring return zone valve,
is used in heating and air-conditioning systems.
The Z-one series consist of a Z1 actuator which is
easily attached to a Z2 (2-way) or Z3 (3-way) valve
body. Z1 actuator is equipped with or without
auxiliary switch.
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.
24V
actuators use a sealed reed switch for end switch,
requiring no minimum current load.
