Introduction to Electro-Thermal Actuator

An electrothermal actuator is a device that converts thermal energy into mechanical energy. It works by balancing the thermal energy produced by an electrical current with the heat dissipated by the environment or substrate.

Electrothermal actuators are primarily used in underfloor heating systems to control the opening and closing of pipes. They are also used in applications like fuel supply livestock, where the temperature of the water or fuel is crucial for the system.

Types of Electro-Thermal Actuator

The Electro-Thermal Actuators produced by our company mainly include the following types:

Floor Heating Actuator

A floor heating actuator is a type of motor that controls the flow of electricity and heat in an electric underfloor heating system. They are commonly used in water underfloor heating systems to ensure an even heat throughout the system.
Actuators are mains-powered devices that fit onto the underfloor heating manifold. When a room calls for heat, one or more actuators open to allow hot water from the boiler to enter the room's pipework

Zigbee Electric Thermal-Electric Actuator

Zigbee electric thermal-electric actuators are used in home heating automation systems. They are commonly used in underfloor heating systems, radiators, and fan coils. Thermal actuators are the main component of thermo-electric actuators. They can perform tasks such as opening and closing valves, operating switches, and releasing latches without an external power source. Thermal actuators use temperature changes to perform these tasks.

230V Normally Closed Type Actuator

A 230V normally closed type actuator is a device that closes the loop when there is no current. It is a component of an underfloor heating system and is used to control manifolds and water valves.

Electric Actuator Valve

An electric actuator valve is a device that controls the opening and closing of valves by converting electrical energy into mechanical motion. They can provide either linear or rotary motion and work with different types of valves, including ball and butterfly valves.

Electric actuator valves are often used on multi-turn valves such as gate or globe and also on ball, plug and other quarter-turn valves. Compared to their pneumatic and hydraulic counterparts, electric valve actuators provide a more energy-efficient, clean, and quiet method of valve control.

Working Principle of Electro-Thermal Actuator

Electrothermal actuator consists of three parts: temperature controller, valve actuator and valve. The room thermostat is installed on the inner wall of the room, and is connected to the electric heating actuator with a cable or without cable(wireless also available). Generally, a 100cm long cable is used to connect the actuator to the selected control point (thermostat, programmer, timer or other remote control device). The actuator is attached to the valve with a nut. When the indoor temperature reaches the temperature set by the temperature controller, the positive thermistor in the electric heating actuator starts to work, heating the thermal expansion device to close the valve, otherwise, the indoor temperature decreases, the thermostat is disconnected, the actuator cools down, and the expansion device shrinks , the valve opens. Generally, it has the function of automatic reset after power failure.

Here is the working principle of thermal actuator, step by step.

The temperature starts rising when the PTC powers on
The solid wax inside the brass housing starts to melt and expand as the temperature gets closer to the melting point
As the space inside the brass housing is unchanged, the volume expansion of wax keeps squeezing the "elastomer bag"
The "elastomer bag" pushes the piston out as there is less and less space left in the "bag"
The temperature starts going down when the PTC powers off. The wax transforms from the liquid phase to the solid phase, and its volume contracts. The occupied space inside the "elastomer bag" is restored. But the piston will not return to its initial position by itself due to the existing frictional resistance between components. An external return spring is required to help the piston go back.

Precautions for using Electro-Thermal Actuator

Here are some precautions for using actuators:

Avoid touching the controller

Touching the inside of the electro-thermal actuator or its peripheral devices can cause electric shock or damage the controller.

Avoid Hazardous Conditions

Electro-thermal actuator are not ideal for use in hazardous conditions, namely around flammable components and emissions. Extreme heat or cold can also present unique challenges.

Avoid mounting downward

Avoid mounting the actuator with it facing downward, especially for valve sizes of 350mm or larger.

Be careful when handling

Be very careful when handling the product. The corners of the product can injure your hands and fingers.

Use an actuator with a brake

If the actuator is not equipped with a brake, injury or damage to workpieces may occur.

Avoid wet hands

Avoid operating or setting the product with wet hands.

Q: Why the floor heating actuator cannot be started?

A: If your floor heating actuator won't start, it could be due to an electrical issue. This could be related to the wiring board or thermostat. You should consult a qualified electrician to check the circuits and assess the issue.

Here are some other things you can try:
