ZM – 12V Series
The Macon actuator ZM-12V is a thermoelectric actuator for opening and closing valves and small valves used in the scope of HVAC technology. The predominant area of application is the energy-efficient room-by-room temperature control in the area of building services and automation. The Macon ZM-12V is controlled by a 12v room thermostat with two-point output or pulse-width modulation.

Function
The actuator mechanism of the Macon ZM-12V with end switch uses a PTC resistor heated wax element and a compression spring. The wax element is heated by applying the operating voltage and moves the integrated ram. The force generated by this movement is transferred on the valve lifter and opens and closes the valve.
