24V UFH Circuit Actuator

The ZL-2033 Valve Actuator is designed to open and close a heating circuit on the underfloor heating smart plus manifold based on whether the circuit is calling for heat.
The valve actuator helps improve the energy-efficiency of the system by allowing individual room temperature control.
The Actuator mechanism uses a PTC resistor-heated wax element and compression spring. The wax element is heated by apply the operating voltage which in turn, moves the integrated ram. The force generated by the movement is transferred to the valve motor which opens and closes the valve.

In case of the normally closed version, the valve is opened/closed by the ram at a steady rate when the device receives its operating voltage. When the devices operating voltage is cut, the device will enter a ‘hold’ period. Once the hold period has finished, the valve will then close evenly by the compression spring.
