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 micro switch. Z1 actuator + Z2 body = Z4 set and Z1 actuator + Z3 body = Z6 set.
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.
