General :

T42 Series Electric Thermal Heating Valves are composed by actuator and valve body; actuator is composed by PTC heat parts and memory alloy swell spring. While need to close the valve, the PTC will be heated by power outside (such as thermostat), the spring is heated and expand to force the valve stem to close the valve. Contrarily, it stops heating PTC to lower the temperature, and then memory alloy swell spring will shrink, open the valve.
