General Function
Thermal actuators are non electric motors that produce linear motion upon temperature change. Upon temperature increase, thermal sensitive material inside the thermal actuator expands pushing the piston to the designed length. When the temperature drops thermal sensitive material inside the thermal actuator contracts or shrinks, providing space for the piston to return.

Precision
An actuator's performance is measured by the amount of distance it's piston travels outward. We measure the distance in thousandths of an inch (.001") and can ensure precision to as precise as five thousandths of an inch (.005")

Piston Travel Range
Thermal actuators can move it's piston to any length between .015" to .500" Piston travel is referred to as "Stroke" or "Motion"

Operating Temperature
Thermal actuators can actuate at any temperature within the range of 30F - 300F (-1C - 149C). Simply choose an actuation temperature of when you want the actuator to function between the stated range.

Unlimited Configurations
With the available temperature range, and the available travel range; thermal actuators can be created to fit any system qualifications. Whether you wish to have a short burst of motion at a specific temperature, or a long variable range, a thermal actuator is the perfect, reliable option for your system.
