Caleffi Hydronic Zone Valves
The Caleffi Zone Valve Z-one, a two position spring return valve, is used in heating and air-conditioning systems. The Z-one series consists of a Z1 actuator which is easily attached to a Z2 (2-way) or Z3 (3-way) valve body. The Caleffi Zone Valve Z1 actuator is equipped with or without a micro 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. Caleffi Zone Valves are perfect zone valves for hydronic heating systems.
