Thermal Actuator
LM-712 The Electro-Thermal Actuator is using for floor heating manifolds,central air conditioning(water system) small valve to opening and close.The normal close actuator is automatic opening after power up.
- Product Introduction
The thermo-electric actuator is installed on the underfloor heating manifolds and controlled remotely by room thermostats to open or close valve for individual circuits/loops.

 |
For a normally closed (NC) thermo-electric actuator, the valve being controlled stays closed when the actuator is powered off. When there is a demand to increase the room temperature from the thermostat, the thermo-electric actuator powers on. The thermal actuator inside the thermo-electric actuator starts heating up, and its piston pushes out as the wax expands. Then the valve is opened, and the hot water starts to flow in the corresponding circuit/loop for this room. As the result, the room temperature increases gradually to reach the set value on the thermostat.
The thermo-electric actuator powers off when the room temperature reaches the set value. The thermal actuator inside the thermo-electric actuator cools down. Then the piston returns to its initial position with the assistance of the return spring to close the valve. The hot water stops flowing in the circuit/loop as the valve is closed.

How does a heating actuator work?
The thermal actuator inside the thermo-electric actuator starts heating up, and its piston pushes out as the wax expands. Then the valve is opened, and the hot water starts to flow in the corresponding circuit/loop for this room.
What is the principle of thermal actuation?
The thermal actuator is a device that uses thermal energy to generate motion or force. There are many types of it, but most work on the principle of thermal expansion. Thermal expansion is the phenomenon where a material changes its shape, area, and volume in response to temperature variations.
