Caleffi Zone Valves for Hydronic Heating
The Caleffi Zone Valves, a two position spring return valve, is used in heating and air-conditioning systems. The Caleffi Zone Valves 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 Caleffi Zone Valves Z1 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.
